Setting the current context to NULL before it is destroyed is normal
application behaviour, and a simple test with and without that call
works for me. I think that I'll try quake3 + OpenAL on my Linux box
after my vacation. But I wouldn't mind if somebody finds the problem in
the OpenAL SI before that... ;-) (the relevant files are al_main.c and
al_mixer.c)
