Old PentiumPro multiprocessor systems had errata that could cause
memory operations to violate the x86 ordering standard in rare cases.
Enabling this option will attempt to work around some (but not all)
occurances of this problem, at the cost of much heavier spinlock and
occurrences of this problem, at the cost of much heavier spinlock and
