New issue 23147 by [email protected]: Deadlock with windowed plugins
http://code.google.com/p/chromium/issues/detail?id=23147

Al hit this deadlock with O3D:

1) plugin (using wm_timer or plugin async callback) calls into renderer to
put up an alert dialog
2) right after, the browser calls ShowWindow on the plugin, which hangs on
the plugin
3) the ViewHostMsg_RunJavaScriptMessage msg from the renderer never gets to
execute on the UI thread, and so the global pump_messages_event never gets
set to cause the renderer/plugin to run a nested message loop, resulting in
deadlock
