Probably, but I'm not sure it would be beneficial. If the thread can be 
interrupted between entering one of the extended functions and the function 
pointer being called, it would be a pretty nasty race condition. OpenAL 
doesn't really say what happens when you call a function for a context that's 
not active (current Windows implementations, if they haven't changed too much, 
would likely crash, silently fail, or succeed using the wrong device).

I'm not sure the cost of an extra lock would be worth it when it could still 
randomly crash anyway.
