The new multiprocessing.managers.SharedMemoryManager spawns a server that delivers memory segments to a parent Python process. If the parent process terminates unexpectedly, we should now make the manager process notice this termination it using the recent multiprocessing.parent_process object (that comes with a sentinel), and shut it down.
