Wow.  Looks like all my other emails are starting to come through.  I
don't know why, but it seems email slowed down to snail-mail pace this

might seem wrong, and have some idea, I'd be infinitely grateful for
any pointers.

To everyone else, I apologize for the barrage of emails I've sent in
the last few days that is just starting to get to the FreeBSD MX
