time.clock() - not usable; I get timings with error interval of about 30% with differences in steps of 100ms

resource.getrusage() - error interval of less than 10%; overall < 0.5% with differences in steps of 10ms

hmm. I could have sworn clock() returned the sum of the utime and stime fields you get from getrusage() (which is the sum of the utime and stime tick counters for all tasks associated with the process, converted from jiffy count to the appropriate time unit), but glibc is one big maze of twisty little passages, so I'm probably looking at the wrong place.

oh, well.
