No, you don't want to add additional concurrent threads of execution.
But he's not doing that, he's just preloading stuff into RAM. It's

My point is that, whatever mmap is doing, your own code
is doing *exactly the same thing*. Passing the
INVALID_HANDLE_VALUE as both your code and the mmap
code are doing is documented as producing an
WowYou put some detail in this response. Thanks so much!
I think I want to stay away from mmap because it uses the disk to
