At this point, you might as well just kill the server, since you won't be
able to do almost anything for the duration of the snapshot.

In practice, undumping the mailbox list is probably a good idea, but not
strictly necessary (atleast with skiplist).  If a mailbox winds up out of
sync with its indexes, when you restore it you can just reconstruct the
mailbox and all will be well (if you have to reconstruct the entire
mailstore, obviously this will take some time).
