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?
