On a system with a copy-on-write optimized os.fork (i.e. almost anything
but Cygwin), no shared memory are needed for shared read-only access.
Anonymous shared memory (multiprocessing.Array) will work on Windows as
well, as handles can be inherited. This must be instantiated prior to
Named shared memory can be used for read-write access to shared memory
created before of after forking.
