Lockhammer: Add a safe mode command-line option #25

Closed lucasclucasdo closed 6 years ago

lucasclucasdo commented 6 years ago

Normal invocation of lockhammer runs with all threads pinned to specific cores in the FIFO scheduler with threads synchronized to only start testing after all threads have successfully been scheduled. This entails many pitfalls including necessitating running as root and the possiblity for poor system responsiveness or even hangs. Add a safe mode option which avoids all of these at the cost of significantly less accurate performance measurment.
