Oh lovely. Now when I do these steps I see in the logs:
Apr 30 08:06:23 tr27n12.aset.psu.edu syslog: PSU mbox-snarf name is INBOX
Apr 30 08:06:23 tr27n12.aset.psu.edu dovecot: Panic: IMAP(tstem38): file 
istream-mail-stats.c: line 75: assertion failed: (ret != -1 || 
stream->istream.eof || stream->istream.stream_errno != 0)
Apr 30 08:06:23 tr27n12.aset.psu.edu dovecot: child 630886 (imap) killed 
with signal 6

I don't get this error for other folders, just the INBOX.

I don't get the timeout leak very often. Maybe 15 times a day total for 
multiple users. I'll do some more debugging of that problem and report 
back.
