test would have turned up bugs in the original code on some platforms.

In both nmh and GNU Mailutils' implementation of MH-format mailboxes,
no locking is done of individual message files when renaming them.

(found through reading the code); there were code paths that closed
the file object and then called _unlock_file() on it.
