After a talk with Timo Sirainen, I have to retract this point. He thinks
that directly feeding the Maildir by bypassing the IMAP agent is not too
bad as long as maildir_very_dirty_syncs=no in Dovecot's configuration.

This is because maildir_very_dirty_syncs=yes will avoid most of the
readdir() calls. This could cause troubles if both softwares access the
Maildir at the same time.
