I had implemented SLOB in userspace, so I resynched and think I
found your problem. Sorry for the attachment format -- this mailer
isn't the best. I'm really computer illiterate when it comes to
userspace...

Anyway, I'm really happy to see you're testing and using SLOB
upstream :) Is there any particular reason that you're using it?

Thanks,
Nick
