Right. On Windows a name is a string, and an UUIDs should be unique to 
the system. If a name exists, CreateFileMapping fails and GetLastError 
returns ERROR_INVALID_HANDLE. If the object alredy exist in the process, 
CreateFileMapping returns a valid handle but GetLastError returns 
ERROR_ALREADY_EXISTS. I'll put som some tests for that to be pedantic,
albeit UUIDs should be unique.
