I was able to do that... and I think the culprit was Samba. That's where the delays were, anyway, and now that I've nuked Samba off that machine it seems not to happen (not that I can reboot yet, but it hasn't happened all day). Looks like login/su were trying to authenticate to samba for some reason... didn't bother investigating, I don't really have any need for Samba on my network anymore (this was legacy from five years ago) so I just kicked it off! -Yaron --
