Why is this better than pure epoll?
- - Supports event source priorisation
- - Scales better with a large number of time events, since it doesn't require one timerfd each
+ - Supports event source prioritization
+ - Scales better with a large number of time events because it does not require one timerfd each
- Automatically tries to coalesce timer events system-wide
- Handles signals and child PIDs
