This hunk makes perfect sense to me, and is fine for maint,
but the other two do not make sense to me yet:
configure ensures that config.status is newer than itself,
thus configure must be older than any .m4 files that are
edited afterwards even without $sleep.

I've read the longish explanation of yours superficially;
if you think it addresses my concern please say so and I will
scrutinize it.

Thanks for looking into this,
