Has anyone else experienced high CPU and machine freezes when exiting the 
frontend with recent revisions? Upon exiting the frontend the main window 
disappears, there is one freeze which stops every everything (mouse, clock 
etc) then it unfreezes for a few hundred ms, followed by a second which 
during which the mouse seems to work but everything else still remains 
frozen. In total the machine is unusable for maybe 10 seconds until 
mythfrontend finally finishes exiting.

Now mythfrontend has always been slow to exit since the QT4 port, Stuart A. 
mentioned something about waiting for a particular thread which never exits,  
but this is different and a lot worse.

I've straced and uploaded the edited result here - http://pastebin.ca/1213812

It's getting extremely irritating now and I'm not sure what the cause might
