Why shouldn't LXAllocShadow be able to return if it succeeded or failed?
As in, just return TRUE if it succeeds, and then the caller maybe
wouldn't even need to separately check for pGeode->shadowArea->offset
being set?

This part looks fine, assuming pGeode->shadowArea->offset is an unsigned
integer
