With this patch, do we still keep a separate machinery that bypasses
the parallel thing altogether in the first place?

I was hoping that the underlying parallel machinery is polished
enough that using it with max=1 parallelism would be equivalent to
serial execution.  At least, that was my understanding of our goal,
and back when we reviewed the previous "fetch --recurse-sub" series,
my impression was we were already there.

And in that ideal endgame world, your "Give '-j1' from the command
line" would be perfectly an acceptable answer ;-).

Thanks.
