Good point. Indeed I mis(spoke|wrote): the fact that it doesn't need
user input makes it *possible* to use `make-thread`, but the fact that
it doesn't block on subprocess output (and instead spends all its time
interpreting ELisp code) makes `make-thread` useless because it will
basically never yield ;-(
Here, we really want to start a new Emacs process (in this specific case
we even *want* that process to be (mostly) fresh&clean, contrary to many
other situations where we'd want a new process that "configured just
like the current process").
