ctx2 would be current for that thread (assuming you mean alcMakeContextCurrent 
for alcMakeCurrent). Both alcGetCurrentContext and alcGetThreadContext would 
return it.

For other threads that didn't have a thread-local context set, ctx3 would be 
current. alcGetCurrentContext would return ctx3, and alcGetThreadContext would 
return NULL.
