any concurrency issues between offlineimap and mutt?

Hi all,

I have just set up offlineimap to run in background in
autorefresh mode.
It synchronizes the entire remote IMAP account to a local
maildir.  I
then work on the local maildir in mutt. That's probably a
very usual
setup, as I understand it.

It indeed works quite well and exactly as I expected. But
now it just
came across my mind that when I am in mutt manipulating the
messages,
what if offlineimap starts a round of synch'ing? The
offlineimap manual
explicitly states that no more than offlineimap instances
should be run
over the same maildir at the same time, does that apply to
concurrent
access from offlineimap and mutt as well?

Thanks in advance for sharing your thoughts on this.
