Yep. You don't have the freedom to remap memory when running JIT-direct on a
32-bit machine. On a 64-bit machine it might work since you can have a full
32-bit address space all to yourself . . . but probably not worth the effort.

Yep. I know. In fact, I think Alex is only about the second person to ask
about it in about 4 years. ;-)

Cool.
