Yes, that's it.

For dovecot.index.tmp that would work, but then there's also
dovecot.index.log.newlock which works as a lock file, it can't be
renamed. It could probably be fixed just by closing all the fds to the
file before rename().

Anyway both solutions get a bit kludgy. Perhaps I could do them with
some #ifdef CYGWIN, but I don't really want to fix those myself.
