The cycles aren't the point. The terminal lines are. Around here,
lots of our users come straight in on terminals, which are limited in
number. This is quite common in lots of places. Autologout timers
*are* useful. I even added one to the csh here. Also, KSH has it,
the TMOUT variable if I remember right.
But what prevents users from unsetting the variable? Additionally you
mentioned that current implementations only work at shell prompts, so
what prevents a user from being idle within an Emacs (my normal state :-).
Are you proposing that the system administrator would compile this
variable into the shell so that it was on? Would you have to have
special privileges to turn it off?
If the issue is users wasting a resource, perhaps the users could be
made aware of that fact. If the administrator wants to blow away idle
users, why not just have a daemon running that kills idle jobs?
If I can be convinced that this is a feature that a USER wants, then I
will glady put it into the shell. But if it is an artifact to make the
lives of a select few better, I don't think I will be inclined to
include it.

I've used it as a user. It's easy to forget to log out when you (alone, or as part of a group) are working on more than one terminal, and those terminals have auto-screenblank feature. In such situations, it helps to turn on autologout (by the shell or by a daemon -- doesn't matter). If you do put it into the shell, please make it unset by default.
