Closing a popup window in Chrome doesn't seem to release memory
<p>I'm seeing some strange behavior in Chrome that I'm trying to verify is intended (or possibly a bug?). Here are the steps I took:</p>

<ol>
<li>First I opened the Chrome task manager, right-clicked and selected "JavaScript memory"</li>
<li>Next I navigated to a test page that has a link that opens a new popup window when clicked</li>
<li>The popup window loads a page that includes a lot of large third-party JavaScript libraries</li>
<li>I checked the Chrome task manager and the JavaScript ram had increased significantly for the test page after opening the popup</li>
<li>Finally, I closed the popup window and waited, but the memory usage basically stayed where it was at.</li>
</ol>

<p>If I clicked the link on the test page multiple times to open multiple popup windows, closing them doesn't seem to lower the memory usage.</p>

<p>I tried this test in IE and Firefox, and when closing the popups in those browsers the memory usage goes down as expected.</p>
