Divizion by zero in T16916

Summary

The test has a history of instability, but I observed another interesting way it's failing.

Steps to reproduce

Running the full test suite resulted in this (partial) output:

Wrong exit code for T16916(normal)(expected 0 , actual 1 )
Stdout ( T16916 ):
Idle CPU consumption too different after event registration: +179769313486231590772930519078902473361797697894230657273430081157732675805500963132708477322407536021120113879871393357658789768814416622492847430639474124377767893424865485276302219601246094119453082952085005768838150682342462881473913110540827237163350510684586298239947245938479716304835356329624224137216% (> +/- 100%)
Before: 0ms
After: 1000ms
*** unexpected failure for T16916(normal)

Expected behavior

The test should pass.
