@rkapsi thx will check
 @normanmaurer - I got this one.
 Interesting, if I run that test from the CLI it's eventually starting to spew these ones...

... many more of the same
```
 @rkapsi - Thanks. Will check. Can I take some of your code you posted and morph it into another form of unit test?
 @Scottmitch yes, feel free.

The readAddress() exceptions are possibly a result of me adding a finally block to that test (because I've been turning it also into an unit test on my end).

```
} finally {
      server.close().syncUninterruptibly();
    }
```
 @rkapsi - Thanks. I have a PR pending approval. I will ping you when I push it upstream and have you verify the changes.

Epoll HttpServer ClosedChannelException death spiral
There appears to be something like a ClosedChannelException death spiral in conjunction with chunked HTTP POSTs and Epoll.

It starts if there is a ChannelHandler that throws an Exception and an another ChannelHandler that catches it and attempts to close the Channel. The server will then spin for a bit throwing ClosedChannelExceptions.

The same test using NIO doesn't exhibit this behavior.
