So, if I'm getting it right, I should follow the following scenario:

- create several threads using pthreads
- for each of them (probably only one of them), call 
GSRegisterCurrentThread() at the beginning
- then, I may call NSView -setNeedsDisplay:, but it currently does not 
work, so I should use performSelectorOnMainThread... instead
OK?


Thank you,
