I clarified the transparent switching section to say that that case 
isn't treated as a disconnect.

It's not a very GL-like thing to do, which is sort of a guiding 
principle of OpenAL, for better or worse.

Then again, GL is building a scene on frame at a time and it's not time 
sensitive, so maybe this is worth considering. It's definitely something 
that should go into another extension (even if one of the callbacks 
becomes disconnect notification and amends ALC_EXT_disconnect).
