I will check on that,

VBL syncing a double-buffer that will be composited later by quartz  
smells in any case risks of troubles for me.

I agree  VBL is nice addition, but using core graphic there seems odd  
as it would bypass quartz (so fine if full screen, but not when  
windowed).
Adding this for full screen context should be ok, but not there  
(costly operation)

I'm pretty sure there is a display manager API for this that would be  
better. will check
