Tangent, but:

Ugh, wow, call-process really is a lot faster than make-process.  I see
now why people disliked my idea of replacing call-process with something
based on make-process, this is a big difference...

There's zero reason it has to be so slow... maybe I should try to make a
better make-process API and implementation which is actually fast.
(without worrying about being constrained by compatibility with
something that's already dog-slow)
