pinning & QEMU processor simulation

I understand we already have ARM processor simulation working, but I bumped into this post...

saying QEMU was not feasible since its dynamic translation is interacts badly with GC moving the ByteArray holding the Cog heap.  

I was just curious if QEMU would be feasible now have object pinning?
