#225: Deadlock/crash in flashsupport closing stream

Comment (by ed at catmur.co.uk):

 It would appear that in thread 1, Flash has asked to flashsupport to shut
 down the pa output device; pa is blocked on the threaded-mainloop mutex.

 The threaded-mainloop mutex is blocked because in thread 2, the mainloop
 is running and trying to get audio data from Flash
 (FPI_SoundOutput_FillBuffer).  However Flash in thread 2 is blocked on its
 own mutex, presumably because in thread 1 Flash has locked that mutex
 preparatory to trying to shut down pa.
