What about just having a numeric64, or changing numeric to support
moving to 64bit sizes when necessary and supported by the platform?
Exactly how much faster would it *really* be?  Have you tested it?  At
what point does it become a 'winning' change?

I'm not sure about 'money' in general but these claims of great
performance improvments over numeric just don't fly so easily with me.
numeric isn't all *that* much slower than regular old integer in the
tests that I've done.
