Did Luke ever send you the Ubuntu crash dump a few months back?  It had
one thread calling snd_pcm_hw_params in alsa_play and another thread
calling snd_pcm_state in alsa_stop, and this caused a crash because, if
I remember correctly, snd_pcm_hw_params frees a structure and then
allocates a new one, and snd_pcm_get_state tried to access the structure
before snd_pcm_hw_params had re-allocated it.

I don't know if this is what Peter is running into, but I don't see
anything in the ChangeLog to fix this.  Having those sorts of crash
dumps should help, although I don't know how to create them off-hand
(ubuntu apparently has tools to generate them and submit them as bugs)
