this may be good for Maildir, but with Cyrus IMAPD, which uses short
filenames like "1432.", "1433.", this *reduced* performance by a few
percent in one test we did.

BTW, the Cyrus filenames are much more friendly for Bacula, since they
keep the size of the Filename table down.  with Maildir *every* e-mail
will have to get its own row in Filename.
