This is the first I've heard of this feature by name, but I assume
it's the same feature that's causing all of these objc_msgSend_rtp
calls to appear in Apple's code on Tiger? Is this documented somewhere?
I strongly suspect that this won't have any kind of fallback
mechanism for 10.3, since the implementation is an absolute branch to
high-memory, and there's nothing on 10.3 that would have implemented
meaningful code at that point in high memory. If there was, I guess
the dispatch would be fast on 10.3, too :)

Will executables built with Accelerated Objective-C Dispatch run on
10.3? I know the accelerated dispatch itself won't work, I was
just wondering if there was some sort of fallback mechanism for
backwards compatibility.
