I've been playing a bit with some code to do this sort of thing,
choosing a set of implementations to enable or disable by trying all the
combinations, and then calculating a quick median. I don't know if I'll
submit that for the initial merge of this patchset -- and in fact all
the current implementations I'm proposing are pretty much okay on
microarchitectures -- but down the line this could be useful as a
mechanism.
