it would be a trivial addition to the telnet daemon, or a shell,
involving the alarm() system call.  Call alarm(300) every time
some data comes through and there you are.  It would also be trivial
to defeat, for instance

	while date do sleep 275 done &

but your casual user who walks away from their session isn't going
to do that.

If your really nice you'd have the timeout be read from an environemnt
variable and share the patch with whoever maintains telnetd or bash or
xterm or whatever it is you decide to patch.
