Yes, moving this stuff to XP code is an excellent idea. There's just
one potential problem, which I am not sure if we need to worry about.
If moving these functions to XP code would require RTTI (real time
type identification) then that would be bad, since RTTI is not
particularly well supported by compilers, and can be significantly
slower. But again, I'll have to dig through my copy of Stroustrup to
figure this out.
