 /*
   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
