Elements: -------- Basic features that cant be implemented from userland sharable between processes. Threads, monitors, xbufs and clocks -> every instance is backed by a device in /dev/evl which allows sharing. Utilities --------- poll is a private-process construct; all poll groups are obtained from a single multiplex device: /dev/evl/poll. They cannot be shared. timers are in essence timerfd directly obtained from clocks, they don't exist on their own, and are process-local too. proxies are backed by a device in /dev/evl to allow for sharing, but this is not something essential.
