Apart from the TCG locking issues (which are conceptually
tractable if anybody cares to try to fix them), the real complication
of multicore-on-multicore is how you handle discrepancies between
the memory models of host and guest, and in particular what
you do if your guest has a stronger memory model than your host:
do you insert barrier insns after every guest load/store? fall back
to not doing mp-on-mp? something else?
