As a continuation of the "locking in AFS sucks" thread, every now
and then AFS gets itself into a state where any program that
tries to lock my inbox on Solaris freezes up. This crippling
behavior is another reason I don't feel like trying to wrestle
with strong file locking for pine.
Right now is one of those times. Something happened to my inbox,
and now Solaris programs that try to do particular kinds of
locking on it just hang. /mit/sipb/bin/pmail is one of those
programs.
I have three frozen pmail processes on xcb right now, and one
frozen one on all-night tool. On xcb I've kill -9'd two of them:
% ps -ef | grep pmail

If pine did strong locking, then people would be able ask fun bug
reports like "why can't I use pine on any of the dialups right
now?" and we'd get to say "because you forgot to sacrifice a goat."
Argh.
