   I'm not fundamentally opposed to a no-overcommit knob, but I think
implementing it properly is more difficult than people think. There are things
that do implied swap allocation (automatic stack allocation and fork() are
two examples) that make this a difficult problem to solve.
   I wouldn't personally want to run a system with such a knob turned on,
however, and I tend to agree with Matt that there are other better ways to
solve the embedded system case.
