Hi Bruno,

This is a bug, but it's not in GNU rm.
I'm not even going to try to work around it before coreutils-6.3.
Given all of the O/S bugs exposed by coreutils' test suite, users
of Darwin 7.9.0 should be rushing to upgrade, if at all possible.

Yes, that's a lot harder to reproduce.
Thanks for all of the details.
