Linux 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.

I realize the above is correct behavior... What bothers me is that (by default anyway) is that it can be used by a limited user to create an an effective denial-of-service attack. Stalling or crashing a multiuser system should IMO (ideally) be something that root, and only root, can do. ;)

OTOH, the presence of tools like dd is why I much prefer Linux to Windows. Experienced users shouldn't have to jump through hoops to do simple things.

Edit: re swap, I wish there were a way of hibernating without it. In my experience it is not very helpful, even on low-memory systems.
