Re: [RFC v4] It is common for services to be stateless around their main event loop. If a process sets PR_SET_IDLE to PR_IDLE_MODE_KILLME then it signals to the kernel that epoll_wait() and friends may not complete, and the kernel may send SIGKILL if resources get tight.

See my systemd patch: https://github.com/shawnl/systemd/tree/prctl Android uses this memory model for all programs, and having it in the kernel will enable integration with the page cache (not in this series).
What about having a dedicated way to kill these type of processes, instead of overloading the OOM killer? This was suggested by Colin Walters [off-list ref]
