Here's where I've gotten to and the result of the git bisect.
git bisect bad

Merges in AutoExpire changes from mythtv-rec2
Before the QThread porting the threads were shutdown somewhat
promptly by use
of a signal. This instead uses the already existing QWaitCondition +
wakeable Sleep() function for the sleeps in both threads.
Note: The porting got rid of the sleep() cancelling signal and
replaced it with
a QThread::quit(), which tells QThread::exec() to exit; but we never
so this is a no-op. Also, the Sleep() function was supposed to exit
expire_thread_running was cleared; but this check was replaced with an
QThread::isRunning() method invocation, which will always return
after the expire_thread_run variable is cleared. This old Sleep()
wouldn't necessarily have worked anyway since expire_thread_running
declared volatile so the check could have been optimized away.
