Because you would want to avoid hitting a "die()" while pushing to
the (N-1)th remote, before you push to the Nth remote?

If there is a "now we have attempted to push to all N remotes, and
know the outcome from these N attempts, summarize them and present
the result" phase in the program, then you'd need to spawn sub push
for N times and then the primary process needs to do the summarizing.

If there isn't any such "post push clean-up" phase, we need N-1 sub
pushes and the last one can be done in the primary process.  If that
is possible, that would be ideal, because it makes N==1 case the same
as the traditional "push to a single remote" case.
