Most processes don't need a TTY. Only those that interact with the
user (shell, term, interactive compile, ...) do, but that's probably a
minority. In particular, everything running in the background
(Flymake, VC...) doesn't, as well as synchronous processes
(call-process etc.). TTY-based communication happens to be the default
for asynchronous processes, but that's more of a historical choice
than a real need.
