The hang on exit while closing the sound devices is unrelated. Probably not a deadlock, only a slow I/O operation and hardware interaction. Hard to trace without the actual device setup at hand.
Now we know that the deadlock is originating from WOverview.
Do you still experience any deadlocks after disabling tcmalloc and profiler from Google PerfTools?
