You must be using csh or some non standard shell, because the Bourne shell
(and the Korn shell too) already have a timeout mechanism!  I'm using a
SVR2.0V1 unix (new AT&T UNIX naming convention: System V Release 2.0 Version 1),
but I'm sure the changes were in previous releases of unix too.  If you
have the source for shell, look for a file "timeout.h" where you can set the
default expiration time (or set to zero if you don't want any time out).
Upon invocation, sh checks to see if the environment variable "TMOUT" is set;
if so, this over-rides the default defined in timeout.h.  On some shells
I've used, the variable was called "TIMEOUT".
