My main concern would be block runtime linking issues. When you use
blocks, the compiler generate call to the block runtime (libSystem on
SL), but does it generate weak symbol or will the program crash at
launch time on 10.5.
Note that a simple test will give the answer, but I don't have both OS
right now.

My understanding is that GCD is only supported on 10.6 and later.
This means you'd need to have some sort of runtime check that would
perform your tasks without GCD if running on a pre-10.6 OS version.

The Grand Central Dispatch headers seem to include availability
macros.
Does that mean we can cross development for a deployment target of
10.5 with a 10.6 base SDK and use blocks and GCD?
