This sample demonstrates named shared memory, both with a file that gets
created to map from, and using the paging file to map from. It implies that
the memory has a client-server relationship, but this is only true in so far
as one process must create the mapping or "shared memory" object.  Other
processes, including the creator, may be allowed access to read/write from it
freely.

Note: client.exe must be in the same dir as the server, unless the path is
specified in the createprocess API call.
