Which reminds me of something else Bill might want to watch out for:
Apple's leak finding tools ('leaks', Instruments, Malloc Debug) do not
work with GC apps. They report so many false positives that they are
unworkable (except for Malloc Debug, which just crashes). So if your
code uses malloc/new/NewPtr of whatever, you'll have a hard time finding
leaks.
Also, I second the recommendation to stay away from finalize. I've used
it exactly twice: 1) to call DisposeHandle() to 2) to call NSLog.
