Delete a directory, crash the system

fsck worked, though I had to boot from a USB image because I couldn't
get into single user.. for some odd reason.

Yeah, I was pretty surprised. I think I tried it like 3 times to be
sure... and yeah, each time... kaboom! Who'd have thought. Do I just
post this to the mailing list and hope some benevolent developer
stumbles upon it and takes it upon him/herself to "fix" this, or where
do I find the FreeBSD Suggestion Box? I guess I should file a Problem
Report and see what happens from there.
