Anything is possible if you're a good enough programmer. Like I said
earlier, there are some users legitimately running long jobs on the
systems in question. Instead of developing a clever program to
automatically kill long running screen jobs, I think it would be better
to be up front with my users and remove screen, rather than let them use
it, only to surprise them later by killing their jobs.
