If it is that commit, they've restructured their code in 
context_state_callback and stream_state_callback.  That patch will not 
apply to OpenAl 1.10.622.  I'm not too excited about using repository 
code (although I use it when necessary).

IMHO, the pulseaudio commit looks like a suspicious/dangerous optimization.
