1 CPUs, running 1 parallel test-tasks.
checking for time-warps via:
- read time stamp counter (RDTSC) instruction (cycle resolution)
- gettimeofday (TOD) syscall (usec resolution)
- clock_gettime(CLOCK_MONOTONIC) syscall (nsec resolution)

new TOD-warp maximum:   -442709 usecs,  00042352e214e2f8 ->
00042352e20e21a3
 | 0.69 us, TSC-warps:0 | 6.89 us, TOD-warps:1 | 6.89 us, CLOCK-warps:0
