[Dovecot] How safe is mbox_very_dirty_syncs?

I've tried turning on mbox_very_dirty_syncs for myself (and a few other
brave souls running 1.0-alpha3 rather than 1.0-stable) again to see what
perfomance gain it gives (see thread
http://www.dovecot.org/list/dovecot/2005-July/007956.html).

Now we aren't running UW-IMAP at all, how safe is mbox_very_dirty_syncs
assuming the only other process writing to mailboxes is our MTA (exim)
which simply appends messages to the end? Is it safer still using
Dovecot 1.0-alphas and the LDA? Does it matter if there are concurrent
connections to the mailbox?

Best Wishes,
Chris
