/* 'CLOCK_PROCESS_CPUTIME_ID' is one of the clock timers for clock_gettime. It
* need not be supported even when clock_gettime is available. It returns the
* 'CPU' time the process has consumed. 'CPU' time is assumed to include time
* when the CPU is actually blocked by a pending cache fill but not time
* waiting for page faults. The attempt is to get a measure of the actual time
* the implementation takes to read a PNG ignoring the potentially very large IO
* overhead.
