Keeping list of all sockets that were sent to child process causes memory leak and thus unacceptable (see #4587). However `server.close()` should still work properly. This commit introduces two options: * child.send(socket, { track: true }) - will send socket and track its status. You should use it when you want `server.connections` to be a reliable number, and receive `close` event on sent sockets. * child.send(socket) - will send socket without tracking it status. This performs much better, because of smaller number of RTT between master and child. With both of these options `server.close()` will wait for all sent sockets to get closed.v0.9.7-release
