If a crashing process was hit with SIGABRT so it dumped core when it ran the machine out of memory, that might be OK... but the problem is that you then can't free up the memory until the core dump is finished, and the machine is in dire straits until then, and that the core dump is likely gigantic. If there was a way to automatically dump a backtrace... (unfortunately core_pattern pipes don't help here because you have to suck in the entire dump to get a backtrace, and if you're out of memory that probably means you have to write it to disk...)
