When running workloads that have high contention in mutexes on an 8 socket
machine, spinners would often spin for a long time with no lock owner.
One of the potential reasons for this is because a thread can be preempted
after clearing lock-owner but before releasing the lock, or preempted after

The mutex-spin_mlock was introduced in order to ensure that only 1 thread

lock-owner is NULL and the lock-count is still not 1, the spinner(s) will
