if a few ms (or even a couple hundred ms) make the difference between avoiding a human and crashing into one you must have a pretty fast robot!

besides, if you are building your super-fast robot control system you have the ability to turn the knob and give yourself absolute control of the CPU

If your super-fast robot control system is capable of running people over,
I'd say you're negligent if you don't find and turn that knob (and a good
few extra ones).

I'd also say that this is an extremely rare case: most Linux users are not
working on systems that can harm people if held up for a fraction of a
second. The needs of the overwhelmingly common case (`don't let buggy code
lock up my system') should govern.
