OK, so it sounds like if we wanted to be completely safe, we probably
need to know that we're in a dovecot Maildir, and then we need to know
where to create the appropriate dovecot-uidlist.lock file whenever
renaming files.

Do you happen to know if the liblockfile (lockfile_create(3), etc.)
.lock strategy is compatible with dovecot's approach?

Thanks
