I do wonder if it would be better to really base the proportional
sampling time based on the actual test runtime (i.e. hardcoding it to be
exec_time_p/2) because that would mean we would have to tune only one
paramter when adjusting the test runtime. But I guess only a few tests
will adjust the test runtime anyway.
