   - Supports event source priorisation
   - Scales better with a large number of time events, since it doesn't require one timerfd each
+  - Automatically tries to coalesce timer events system-wide
   - Handles signals and child PIDs
 
-  TODO:
-
-  - Detect forks and return ECHILD
-  - quit hooks
+  TODO: rename mute to enable?
