Review comment:
I think this race condition was particularly severe since we do the
listOffsets request pretty much immediately after creating the topics, whereas
whatever we're doing with that topic next will not be until the rebalance was
completed.
AFAIK we've never had any users report subsequent operations failing after
the first rebalance due to not-yet-fully-created topics, but it could have just
slipped past us
