The question comes from experience preforming similar
synchronization proposals for requirements lists, translations, data
file normalization, et cetera. Specifically, if you update the msync
repo and that triggers change proposals for all your module repos,
but then core reviewers don't get around to approving at least some
of those before the next change merges to the msync repo (especially
possible if you approve two msync changes at roughly the same time),
will it properly update the existing but not-yet-merged changes it
previously proposed rather than creating new changes?

Also, does msync know to take advantage of the on-disk cache of git
repositories on our job workers, or does it clone them all over the
network every time it runs? The latter can lead to additional
