The killer program was introduced to fix problems reported at schools,
with leftover processes and running out of resources.  I hope we can
make sure the lenny release fixes this problem, as it affect a lot of
schools.

Another approach would be to teack killer to look for host group
membership, and only run when the current host is in a group.  It
would allow schools to enable it on single hosts using lwat and LDAP
group memberships.

As far as I know, there is no need to change this.  The thin clients
will ask for more swap when running out, and the swap will be added in
32MB increments. :)

Happy hacking,
