4d) First wait and see if 4c is implementable; if not, fall back to 4b.
Well, I agree on everything and would directly vote for 4b, but instead I ask: what is the true problem here? If callbacks are serialized, what's the problem in allowing any thread to call CGA functions? There is a chance that some windowing system allows this. For example, mutual exclusion could be required for drawing on a surface, but not for registering a callback, so while a thread is drawing, another could be allowed to register callbacks. Could someone explain what are the problems? Vincenzo
