Force refresh of maildirs to detect changes immediately

[Jeff Peeler]

Hi all,

Is there a way to make mutt recheck maildirs outside of mutt? The idea
is to be able to have offlineimap's postsynchook update mutt such that new
emails are noticed immediately. I've read that mutt will recheck upon
any keypress, but that isn't helpful here. I thought that adding timeout
and mail_check options to .muttrc would suffice, but those options must
only be for IMAP folders only.

If code changes are necessary, it seems that watching for a signal would
be the easiest approach. I don't understand why the mailboxes aren't
just watched constantly anyway using something like inotify.
