Yep, I managed to get a repeat test case.  Of course on Cyrus 2.4+ the cost of an errant EXPUNGE command isn't very high, because it doesn't trigger a repack unless it actually makes a change which sets the MAILBOX_NEEDS_REPACK flag on the index header, so it's only going to affect people on ancient Cyrus.

I have no idea why they're doing an EXPUNGE every time though.
