Devel::NYTProf only records timings from one clock at a time. (It's nice
that that's configurable, to use any of the clock_gettime() clocks.)
It ought to be possible to configure NYTProf to record multiple clocks
simultaneously. A naive use of times(), in a very simple profiler,
gives both real time and CPU time, with CPU time split into user-mode
and system-mode. NYTProf could equally well record both CLOCK_MONOTONIC
and CLOCK_PROCESS_CPUTIME_ID. The comparison of the two sets of timing
data, on the same subroutine executions, provides useful information.
