Using a locking microbenchmark on the same system, the locking

At this level stddev would be nice to have, as these sort of things have
a lot of variation.
Out of general interest, are these microbenchmarks available? Would you
care to add something like that to perf-bench? I assume they would
probably be x86 specific.
Ingo has asked similar question and he suggested doing an user-space
implementation in perf bench. I will take a further look at that when I
have time.
