I added the call to mlockall() (it did have to be run as root)

I don't get how that is expected. The "CPU bound task" is now basically
guaranteed to not be doing anything that requires disk access, so the
iowait should be 0 for the "CPU bound task"
the purpose of mlockall() was not to solve the problem, it's intention is only to reduce side-effects in the test scenario
