tests/beakerlib/Tuned-takes-too-long-to-reload-start-when-ulimit/runtest.sh should be more clear

Test checks if there is delay after tuned start.

It exploits small time window among beakerlib commands which is not clear at first look.

Maybe just add sleep .5 and more comments will help. Or maybe use timeout command in combination with exploit of "race condition".

Yep, I think you should use the timeout command or similar mechanism. Now you are only checking that the 'sysctl' log message was removed, which IMHO was.
