That sounds like the first law of debugging to me :-)

I was also starting to think in the NFS direction. It's one of the reasons I
use Maildirs. My setup is a bit convoluted too. This machine (the one now
running -current and hanging) plays NFS server. The mailserver mounts the
maildir and writes mail into it.
Now, the 'hangs' appear to be somewhat random, I can open a few mailfolders
without issues, then suddenly I get a hang if I try another one. Also, I
notice that when I send a mail when I'm in a folder which is set up to save
mails in itself (what a ridiculous sentence), they don't get saved until a
while later.
I'm going to fiddle a bit with my setup and see if I can reliably reproduce
hangs. 'Random' is very difficult to debug, I know :-/

So who is this mysterious other person? :-)
I'll get back with some more concrete information as soon as I have some.
It's an intriguing challenge.
