Console lock solution.

[Stephen Ware <steve_(_at_)_inserted_(_dot_)_net>]

Howdy,
I often log into my home machine (OpenBSD 2.9) from work for varying
purposes. I'm often called away for all sorts of emergencies (start
bars disappearing, "the internet doesn't work!", etc :-), and forget to
log myself out. Recently, I think there's been some people messing
wiht my machine when I do such stupid things, and I'm after some way
to lock the console after a certain ammount of idle time, or some
such. I'm often running editors/mail clients inside screen, so I'd like
something that was able to detach that, or run so as it doesn't effect
the way the process runs.
The other problem I can see, is if someone grabs my machine before
that idle time comes through, which would reset it.
Is there any thing that can do such a thing? I'd prefer something that
just prompts for my password, as opposed to logging me out. Is this
possible, or should I just remember to log out each time I walk away?
(I have a terrible memory for details). I'd like to implement
something before I walk away from an su'd session, heh.
Many thanks for any ideas you can throw my way.
