sig11 with autocreate feature

[Simon Matter]

I just discovered a problem with the autocreate patches from
http://email.uoa.gr/download/cyrus/cyrus-imapd-2.2.3/ which have been
discussed today on this list. Since the maintainers of the patches also
read the list I think it's okay to mention this here.
When the createonpost feature is set, then a new mailbox is created if a
mail is delivered to a non existent mailbox via lmtp. Now I discovered
that whenever I send mail with postfix to such a nonexistent mailbox, the
box is created on the fly but the mail is not delivered until the next
time postfix flushes the queue. I tried to figure out what's going wrong
but was unable to find it. An strace of the dying lmtpd process can be
found here

this is from the logs:
