[Clusterusers] NIMBYed nodes

Yes. We have never had a problem with that, however, because if nobody
logs in as you, they can't accidentally kill your jobs, and it's
unlikely that anybody would maliciously do so.

Also BTW, there's a dead link to documentation in your notes that one of us must have posted at http://sites.hampshire.edu/ci-lab/2012/08/14/introduction-to-using-the-cluster-with-tractor-2/ ... the bad link is fly.hampshire.edu/docs/Tractor_1.6.3/).

Sometimes I'll start one of these, check in on it regularly for a while, and then check in less frequently if it's not doing anything really interesting but I'm not ready to kill it in case it might still do something good. Then sometimes I lose track. Right now I have nothing running, and any nimbying that I've done can be unnimbyed, although I'm not 100% sure what I may have left nimbyed.

If somebody is inspired to do this, then it would also be nice if the command for numbying/unnimbying was more straightforward than the current one (which takes a 1 or a 0 as an argument, which is a little confusing), if it returned a value that made it more clear what the new status is, and if there was a simple way just to check the status (which maybe there is now? if so I don't know it).
