The current code removes streams from the priority tree as soon as they are closed (subject to the removal policy). This may lead to undesired distribution of resources from the peer's perspective.\r\n\r\nModifications:\r\n- We should only remove streams from the priority tree when they have no descendant streams in a viable state.\r\n- We should track when tree edges change or nodes are removed if inviable nodes can then be removed.\r\n\r\nResult:\r\nPriority tree doesn't remove closed streams until descendant are all closed, or there are no descendants.","created_at":"2015-03-27T18:41:15Z","updated_at":"2015-03-27T19:54:42Z","closed_at":null,"merged_at":null,"merge_commit_sha":"99b1ef10d53ab34c6ba7ac6bad90d3a7668b231e","assignee":{"login":"Scottmitch","id":7562868,"avatar_url":"https://avatars.githubusercontent.com/u/7562868?v=3","gravatar_id":"","url":"https://api.github.com/users/Scottmitch","html_url":"https://github.com/Scottmitch","followers_url":"https://api.github.com/users/Scottmitch/followers","following_url":"https://api.github.com/users/Scottmitch/following{/other_user}","gists_url":"https://api.github.com/users/Scottmitch/gists{/gist_id}","starred_url":"https://api.github.com/users/Scottmitch/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/Scottmitch/subscriptions","organizations_url":"https://api.github.com/users/Scottmitch/orgs","repos_url":"https://api.github.com/users/Scottmitch/repos","events_url":"https://api.github.com/users/Scottmitch/events{/privacy}","received_events_url":"https://api.github.com/users/Scottmitch/received_events","type":"User","site_admin":false},"milestone":{"url":"https://api.github.com/repos/netty/netty/milestones/112","html_url":"https://github.com/netty/netty/milestones/4.1.0.Beta5","labels_url":"https://api.github.com/repos/netty/netty/milestones/112/labels","id":1005380,"number":112,"title":"4.1.0.Beta5","description":"","creator":{"login":"normanmaurer","id":439362,"avatar_url":"https://avatars.githubusercontent.com/u/439362?v=3","gravatar_id":"","url":"https://api.github.com/users/normanmaurer","html_url":"https://github.com/normanmaurer","followers_url":"https://api.github.com/users/normanmaurer/followers","following_url":"https://api.github.com/users/normanmaurer/following{/other_user}","gists_url":"https://api.github.com/users/normanmaurer/gists{/gist_id}","starred_url":"https://api.github.com/users/normanmaurer/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/normanmaurer/subscriptions","organizations_url":"https://api.github.com/users/normanmaurer/orgs","repos_url":"https://api.github.com/users/normanmaurer/repos","events_url":"https://api.github.com/users/normanmaurer/events{/privacy}","received_events_url":"https://api.github.com/users/normanmaurer/received_events","type":"User","site_admin":false},"open_issues":75,"closed_issues":18,"state":"open","created_at":"2015-03-04T09:22:23Z","updated_at":"2015-03-27T18:58:38Z","due_on":null,"closed_at":null},"commits_url":"https://api.github.com/repos/netty/netty/pulls/3543/commits","review_comments_url":"https://api.github.com/repos/netty/netty/pulls/3543/comments","review_comment_url":"https://api.github.com/repos/netty/netty/pulls/comments{/number}","comments_url":"https://api.github.com/repos/netty/netty/issues/3543/comments","statuses_url":"https://api.github.com/repos/netty/netty/statuses/346de6ddf7d90baa6d33aeb66dd9372fd77b4b58","head":{"label":"Scottmitch:http2_priority_tree_closed_stream","ref":"http2_priority_tree_closed_stream","sha":"346de6ddf7d90baa6d33aeb66dd9372fd77b4b58","user":{"login":"Scottmitch","id":7562868,"avatar_url":"https://avatars.githubusercontent.com/u/7562868?v=3","gravatar_id":"","url":"https://api.github.com/users/Scottmitch","html_url":"https://github.com/Scottmitch","followers_url":"https://api.github.com/users/Scottmitch/followers","following_url":"https://api.github.com/users/Scottmitch/following{/other_user}","gists_url":"https://api.github.com/users/Scottmitch/gists{/gist_id}","starred_url":"https://api.github.com/users/Scottmitch/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/Scottmitch/subscriptions","organizations_url":"https://api.github.com/users/Scottmitch/orgs","repos_url":"https://api.github.com/users/Scottmitch/repos","events_url":"https://api.github.com/users/Scottmitch/events{/privacy}","received_events_url":"https://api.github.com/users/Scottmitch/received_events","type":"User","site_admin":false},"repo":{"id":21251366,"name":"netty","full_name":"Scottmitch/netty","owner":{"login":"Scottmitch","id":7562868,"avatar_url":"https://avatars.githubusercontent.com/u/7562868?v=3","gravatar_id":"","url":"https://api.github.com/users/Scottmitch","html_url":"https://github.com/Scottmitch","followers_url":"https://api.github.com/users/Scottmitch/followers","following_url":"https://api.github.com/users/Scottmitch/following{/other_user}","gists_url":"https://api.github.com/users/Scottmitch/gists{/gist_id}","starred_url":"https://api.github.com/users/Scottmitch/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/Scottmitch/subscriptions","organizations_url":"https://api.github.com/users/Scottmitch/orgs","repos_url":"https://api.github.com/users/Scottmitch/repos","events_url":"https://api.github.com/users/Scottmitch/events{/privacy}","received_events_url":"https://api.github.com/users/Scottmitch/received_events","type":"User","site_admin":false},"private":false,"html_url":"https://github.com/Scottmitch/netty","descri
