(1) is the event handler. (2) is the event queue.

L₁ 
▻ Event loop begins to idle and wait for an event.
▻ e₁ is placed in the event queue and immediately dispatched to the event handler.
▻ While e₁ is being processed, e₂ and e₃ are placed in the event queue.
▻ The duration of time between when L₁ starts and
e₁ is dispatched will be measured as the event provider's idle time.

L₂
▻ The event provider is entered and immediately receives 
events e₂ and e₃.
▻ While e₂ and e₃ are being processed, e₄ is placed in the event queue.
▻ Because an event was waiting in the event queue, the idle time does not increase.

L₃
▻ e₄ is immediately received and processed.
