An interesting possibility would be for, once backing store is full, if any new page should go to swap, the LRU page on the backing store should be "forgotten" and freed; if a "forgotten" page was ever used again, such process would receive the SIGBUS signal. That would keep the system running happily even if processes leak arbitrary amounts of memory.
