I'm thinking a PDF that may be left open on purpose to serve as reference to something, a browser window, etc. Are you then proposing to use the LRU policy to do the killing? I'm thinking that a popup with a cancel tied to a timeout may be a good idea. Once it is not allowed to be killed, it should not try to again for the session, or at least for a very large increase in query time.
