TestServer.listen_and_accept/0 opened a TLS listen socket that nothing closed, so every HTTP/2 fuzz scenario left a listener behind: 200 scenarios grew the tcp_inet ports from 1 to 201 and the processes from 125 to 527. The accepting task now closes the listen socket once it has accepted the single connection it serves, and the same 200 scenarios end with 1 port and 127 processes.
