/* QEMU doesn't strictly need write barriers since everything runs in
24 24 
 * lock-step.  We'll leave the calls to wmb() in though to make it obvious for
25 25 
 * KVM or if kqemu gets SMP support.

 * In any case, we must prevent the compiler from reordering the code.
27 
 * TODO: we likely need some rmb()/mb() as well.
