Stupid question: is it possible to teach it to recognize the deadlock ? If I understand things right "nice behaviour" happens when we don't have the deadlock and the deadlock occurs not very often. So we might check once a second whether we have been low on memory for a while with a lot of swap available and if so revert to "bug-proof" behaviour.
