Fair enough, also the alarm() in the test library pid is set before we
run the test setup, so if the test setup would take a few seconds we
will be off with the calculation. Although that could be fixed by
calling heartbeat before we run the loop in testrun(), which I guess
should be done anyway. That in turn would allow for your patch to have
the clock_gettime only in the heartbeat function, right?
