Uh? Doesn't ex_threads2 draw to the display from 6 different threads and none of 
them created the display, and it still works?

al_set_current_display() will make the context current to the thread calling the 
function, using pretty much the same routines on all three platforms: 
glXMakeCurrent/wglMakeCurrent/makeCurrentContext
