[Dovecot] imap processing spinning on the CPU

[Daniel J. Luke]

Version: 2.0.2
OS: Mac OS X 10.5.8

IMAP Client: Apple Mail.app on 10.5.8 

Since upgrading to 2.0.2 I've noticed one user ends up with 4-5 imap processes all using as much CPU as they can get.

I know of one other person who is seeing this on a FreeBSD server (that person moved back to dovecot 1.2 which 'solved' the problem there).

I didn't notice anything in the list archive about this, but maybe I missed it.
