   > I suppose it's a matter of style.

   Just to clarify, since I've just realised we're talking about
   two independent things here:

   1. "catch/loop/throw" vs "let/test/loop/set" is indeed a
      matter of style (but you've probably convinced me to
      prefer the latter).

Yeah, that was my meaning.  I look forward to learning why
‘run-with-idle-timer’ is even necessary (my only experience w/
that is in zone.el func ‘zone-when-idle’).

   2. It's the short timeout to accept-process-output that I'm
      supposing hurts performance, but it can also be lengthened
      using the first idiom.

Why does a short timeout hurt performance?  My understanding is:
large timeout => more time for subproc to do its thing => bigger
and fewer chunks of input => less overhead relatively => better
overall performance.

      [timeout value gyrations]

Sounds somewhat cargo-cult.  Just like Emacs, i suppose... :-D
