You need a timeout for nntp-open-connection, but
nntp-connection-timeout does not work for open-network-stream because
in both Emacs 20 and XEmacs 21 the timer is ignored when connecting.
Maybe it works for an external program (for example, (setq
nntp-open-connection-function 'nntp-open-telnet)). I never try it.
