The first thread will pause every 16 cycles for 10000us. This will show up in the max values for all other threads when the final results are printed: # signaltest -q -D 2s T: 0 ( 4517) P: 0 C: 3121 Min: 5 Act: 8 Avg: 8 Max: 19 T: 1 ( 4518) P: 0 C: 3121 Min: 5 Act:10065 Avg: 639 Max: 10073 We could also remove the sleep but then the system gets fully loaded by the test. Furthermore, we would keep the path pretty hot and that's not ideal if one wants to test the eratic signal behavior. So only consider the first thread for the stats.
