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.
