effective tomorrow, there will be a new limit for longjobs of 3 days.

why are we doing this? basically, jobs that run forever are a problem
because of two reasons:

1. fair division of resources is worse the longer the jobs are.
2. when we need to do maintenance on a cluster node, we would want to
avoid killing your jobs. so we would have to disable the node (so no
more jobs get started there) and then wait until the last job has
finished. if a job takes 10 days, we would have to wait 10 days and the
node would be usable by others.

if you have any questions or comments, you are welcome to share your
thoughts with us.
