1. Change the port for server_poll to listen to avoid "address in use" conflict between test/server and test/server_epoll, and add port as an argument for test/client to send message 2. As posix-spwan may fail, change the fixed number of processes to spawn to the number of processes successfully spawned in server_epoll
