On slower machines, startup can take some time,
set last values to current [us]time before actual test.
This caused test to fail, because first delta contained
time spent by test starting up:
getrusage04 0 TINFO : utime: 999us; stime: 6998us
getrusage04 0 TINFO : utime: 999us; stime: 6998us
getrusage04 1 TFAIL : stime increased > 1000us: delta = 6998us
