Indeed, using --overwrite is generally a bad idea unless you're fixing
a mistake 2s after you pushed it and nobody else pulled it yet.

That said, however, the train does record commit IDs rather than
revnos, which means it will detect changed commits and include those
for rebuilding, so the train won't give you any hassle if you're using
--overwrite on your MPs.
