Huh?  This is called only once during compilation.  What evidence do you have
that CreateFileMapping is faster than VirtualAlloc here?

We are not sharing memory across processes so we don't really need to create a
named memory-mapped object. I would prefer to keep the memory object anonymous
rather than hardcoding a name that could be accessed by other processes.
