Trying to work through the hang problem that I've been experiencing with
v7.0, and keep adding new tools.  Tom suggested lsof, and running it
against the postmaster shows the above 'error' .. once it happens, it
doesn't appear to go away.  Last hang, had two of those errors ... don't
know if they mean anything or are related, but figured I'd ask:
