I think this applies to the original delivery, but not necessarily to
subsequent manipulation of maildirs.

For example, the message flags are stored by appending them to the file
name.  If two MUAs concurrently scan the maildir for messages, then try
to set a flag on one message, a race is possible.

I observed wierdness when I tried to access my mail both by IMAP (the
with Dovecot as the IMAP server) and directly reading the underlying
maildirs with mutt.  That was part of the reason why I gave up on IMAP
entirely, and instead read over ssh and mutt locally on the server.
