Note, if you really are adamant on your solution, I can write them up,
test them, and get them out for this merge window. I really want a
solution for the int3 emulate calls, as there is a real bug here that
they fix.
But I will say, I still prefer Peter's solution. Maybe in the future we
can revisit it again.
