Please forget the question, I've just started running mprime for a
stress test and that too is hitting 400% (deliberately using all 4
cores) so it isn't only rust that can do this.  I still don't recall
ever noticing this sort of CPU % before, but it clearly isn't a
rust-specific feature.

In my seventh decade astride this planet, and as my own cells degrade,
there are some things I cannot do now: skydiving, marathon running,
calculus. I couldn't do them in my 20s either, so no big loss.
