Won't the operating system close any open file descriptors (including sockets) when the process terminates?

Yes it will. But suppose you are killing a server process with clients connected, then the clients won't notice that the server is gone before timeouts.

Ah yes the old "if it is in any way imperfect you are stupid to use it" argument.

If a process is killed then the socket will send RST to the peer, where as if the process calls close or shutdown on the socket, then the socket sends FIN. There is no timeout needed. A timeout situation will only occur if the power is dropped or the network cable removed.
