The stall timer looked only at log growth, so a parallel check.sh that
prints nothing for 9 minutes while working ended PREGATE_STALLED (FOUN-63).
supervise now samples the process group's CPU time each second and treats
growth of at least a tenth of wall time as liveness. An idle hang still
stalls; a hang that burns CPU is left to --timeout.
