A new version of the real-time Linux scheduler called SCHED_DEADLINE has been released on the Linux Kernel Mailing List. For people who missed previous submissions, it consists of a new deadline-based CPU scheduler for the Linux kernel with bandwidth isolation (resource reservation) capabilities. It supports global/clustered multiprocessor scheduling through dynamic task migrations. This new version takes into account previous comments/suggestions and is aligned to the latest mainline kernel. A video about SCHED_DEADLINE is also available on YouTube.

If Linux gets exhausted of RAM, then the requesting application is killed and an OOE (out of memory exception) raised in the event logs.
What Linux usually does (unless vm.oom_kill_allocating_task is set to 1) is attempt to kill programs that look like memory hogs, using some kind of heuristic.
Not quite true, that's what Linux should do.
In my experience, that heuristic knocks out the offending program about half the time... The other half the time, it knocks out X.
