In ITS I put limits on the size of output buffers in interactive remote login
so as to prevent that sort of problem.  The small buffer ensured that if you
typed C-c or C-z, you wouldn't have to wait as lots of output arrived
before the program stopped generating more output.

In Emacs, we want large buffers for the situation where a Lisp program
is running and goes for some time without allowing subprocesses output
to enter.

Perhaps if we study the cases where we need a large buffer and the
cases where we don't want a large buffer, we could find a criterion to
distinguish.
