I suppose this could be done somehow. But OSDispatch is called by EVERYbody.
Finder, Backgrounder, Window Manager (well, the MF version anyway). OSDispatch
is a large-scale commitment on Apple's part in terms of engineering. It would
simply be too much effort now to back out for a minor revision like 6.0.6.
Now, 7.0, that's another matter, but then again, under 7.0, you KNOW MF is
running.
