It looks like Crtl-C is incorrect here to stop Memcached gracefully. To stop gracefully it needs
kill -SIGUSR1 <pid of memcached> where <pid of Memcached> is the process id of Memcached but SIGUSR1 is a Unix/Linux signal for inter process communication and it is not used in Windows. This is why my testing does not work in Windows.
