GCD is very useful, but from what I see just not for real-time
applications. And no, it doesn't necessarily come to a "halt", but it
can be affected, which is what you really DON'T want in a real-time
situation.

If everything scheduled by GCD across all CPUs comes to a halt when
you hold down the mouse on a dialog what good is it then? That sounds
a bit like a flashback to MacOS 9 times to me... or am I
misunderstanding what you are saying? (still waiting for my copy of
SL..).

Ehm, you know that GCD is running at the main thread level? Which
can be
blocked by UI operations, etc. That doesn't seem like a wise choice
for
real-time processing. OpenCL also doesn't have a threading mode, so
you
tasks will be shared among all the others and your latency becomes
unpredictable.
