No, there are almost no opportunities for native. Especially with SMP, doing on-line code switching is really really nasty. You basically have to shut down all CPU's to make sure there are no races with other CPU's executing the code while it's being rewritten. I'd be very very nervous about it. It would have to be some major performance feature for it to make sense over a simple "switch function pointers around" approach.
