This patch fixes a race condition that happens in winecfg (the only place I
ever see this crash) caused by the messageThread being alive after the
driver has been closed.
So -- on drvclose/coreaudio_waverelease -- I wait for the messageThread to
finish -- verify it has finished -- and clean it up.
I would prefer to wait for the messageThread to start in coreaudio_waveinit
But cannot because the messageThread will not start executing (due to loader
locks) this leads to deadlock (if you try to wait for a signal that the
messageThread has started).
There could be problems with startup and playing sounds (really fast) -- but
im not sure about that yet...
