We don't really bother. We run the script overnight (over several
nights) to minimize storage utilization and we haven't run into a
problem. I haven't looked at the code in a while, but as I recall the
rename operation is fairly atomic.

In short: it doesn't take long to move a box. The worst thing that I
could imagine would be a momentary outage for a single user (``Mailbox
does not exist'' or similar). This sort of error (if it does occur in
the wild) would clear almost immediately.
