The attached mail from 'caldo.demon.co.uk!forsyth'
to 'plan9.bell-labs.com!9trouble' alias `local!9trouble'
failed with error '/bin/upas/deliver: opening mailbox: permission denied'.
the gist of the message (which i've resent to another address)
was: if you use filterkit's pipeto with
if(isspam)
spool /mail/box/$USER/spam
ensure chmod a+rw on /mail/box/$USER/L.spam
or each delivery of spam will take a little time.

Note that this says L.spam and not L.mbox,
a fact that I completely missed on first few readings.

A dichotomy twixt tools that shouldn't be there. It looks like upas/fs always locks
L.mbox but that upas/deliver and upas/send lock the file L.(basename of mailbox being used).
Usually, they're the same but if we're delivering into other mailboxes, they aren't.
I'll make everything lock /mail/box/<user>/L.mbox and avoid the problem all together.
I'll run it locally for a while since I'm sure to generate at least one deadlock
along the way.

Perhaps I'm picky. But I'd suggest changing the lock file
to be /mail/box/$user/Lock
Then it'd be clear that it does not refer to mbox in particular.
Thanks for the fix anyway.
