Well, I'm working off the alpha code which does the direct
return to rei.  I haven't gotten it working, yet--got distracted...

You lose a couple of things by skipping the return to syscall,
but presumably the fresh new process won't have received a signal,
nor will it want rescheduling.  This leaves a possible call to
sc_debug, another to addupc_task for profiling, and one more
to ktrsysret.
