Nathan Beyer commented on HARMONY-3246:
---------------------------------------

I can test that these changes are passive on P4 platforms, but I can't test these changes on P3 platforms at all since there are lingering 'mfence' assembly instructions being inserted that prevent the VM from starting at all. It would seem that we need to eliminate those changes first before we can do this.
