"Process" in Emacs just refers to a "process object" -- it's not tied to
the Unix concept of a process, really.  (But Unix processes are
interacted with via Emacs process objects normally.  :-))

An Emacs process object is something that perhaps gives you bytes and
might accept bytes, so it's a network connection, a UDP server, a
socket, a pipe, a tty, a serial connection or a Unix process.  (And
probably other things I'm forgetting.)

If you could come up with a minimal test case for that, that'd be nice.
