Using qemu_cond_timedwait is a hack for not properly broadcasting the
condvar in flush_threadlet_queue.
I think Anthony answered this one.
I think he said that the code has been changed so I am right? :)
You're right about the condition we check in the exit path but the
timedwait is needed to expire an idle thread.
