But "git-gc" without the --prune doesn't delete any objects.  So it
should always be safe to use git-gc even if there are repositories
that are relying on that repo's ODB.  It's only if you use git-gc
--prune that you could get in troudble.  It might delete some
packfiles containing objects needed by B, but only after consolidating
all of the objects into a single packfile that contains all of the
objects that had always been in A's ODB.

So I don't see why this wouldn't work.
