Rather, tcg doesn't make sense for shared memory smp.  But we knew that
already.
In think TCG SMP is a hard, but soluble problem, especially when you're
running guests used to coping with NUMA.

Do you mean by using a per-cpu tlb? These kind of solutions are generally slow, but tcg's slowness may mask this out.

TCG interacting with third parties via shared memory is probably never going
to make sense.

The third party in this case is qemu.
