Running parallel benchmarks seems to fail sometimes because chrt permissions are lost? #469
Description
I noticed that parallel runs on Navajo started failing suddenly, because chrt -r 1 running permissions are lost. Not sure if this happened because of an upgrade, but adding an explicit test that chrt -r 1 is runnable and printing an explicit error message in this case would make it easy to debug and fix.
taskset --cpu-list 0 chrt -r 1 ls
chrt: failed to set pid 0's policy: Operation not permitted
