Well, if you don't mind resolving the race conditions that you're going to
have, you could possibly do that. In practice though, unless it's a very
small hash table, it's going to need to be accounted for in the sizing
calculations in CreateSharedMemoryAndSemaphores, which means you might
as well create it during that function too.
