I guess I figured it would work somewhat differently...perhaps because of
the way elm (which I used for 10 years and just dropped for mutt) handled
at least your main spool folder, and would complain to you if
/tmp/mbox.fairlite was present and you tried firing up a new session, etc.
Your delivery example does show the flaw in my logic, especially keeping in
mind WHY elm used /tmp/mbox.fairlite :) And that was only on the main
spool. At least mutt is polite and just informs you of a change, and
doesn't bail on a "corrupt" mailbox. :) :)
For what it's worth, I did talk to someone else about this and they said if
you open, say:
1) mutt -f folders/blip
2) mutt -f folders/blip
3) mutt -f folders/blip
And if you make any changes, if you close 3 and then 2, and then 1, you're
fine, and notified appropriately, etc. But if you close 1 first, 2 and 3
will core dump. At least that was my understanding, and I haven't seen
this exhibition of behaviour personally. I thought I'd mention it while
we're on a similar topic.
I'm actually more worried about the double-message index display but I
caught the other day. :)
Thanks for straightening out the locking deal for me.
