The issue here isn't that it's been flushed in realtime (since it's for the current connection that did the delete), but rather that the EXPUNGE is being issued between commands, rather than within the MOVE.

That being said, fixing that does not fix evergreen from crashing - I wonder if libetpan is confused by something or there is another issue here:

A related problem in evergreen is if we go to the trash and move a message to the inbox, the client freezes - if we hit 'm' to try to move another message, nothing happens, and after the libetpan timer expires, the client exits.

Note: Both the delete issue and the moved issue seem to be caused by an untagged STATUS being sent when we being IDLE, as they are resolved by the fix for [LBBS-116].
