Concretely, what is this "knob"? Is it a per-process variable? If
so, we could make Emacs set it, with a Lisp function to specify the
value.
What is the precise definition of "no more memory left"?
The thrashing that I observed did not immediately kill any process.
Rather, it continued for minutes before doing so. So I don't think
there was "no more memory left on the system", because if that had
been the case, Linux would have known it immediately.
