162<p><code>removeListener()</code> will remove, at most, one instance of a listener from the
163listener array. If any single listener has been added multiple times to the
164listener array for the specified <code>eventName</code>, then <code>removeListener()</code> must be
165called multiple times to remove each instance.</p>
166<p>Once an event is emitted, all listeners attached to it at the
167time of emitting are called in order. This implies that any<code>removeListener()</code> or <code>removeAllListeners()</code> calls <em>after</em> emitting and <em>before</em> the last listener finishes execution
168will not remove them from<code>emit()</code> in progress. Subsequent events behave as expected.</p>

171<p>Because listeners are managed using an internal array, calling this will
172change the position indices of any listener registered <em>after</em> the listener
173being removed. This will not impact the order in which listeners are called,
174but it means that any copies of the listener array as returned by
175the <code>emitter.listeners()</code> method will need to be recreated.</p>
176<p>When a single function has been added as a handler multiple times for a single
177event (as in the example below), <code>removeListener()</code> will remove the most
178recently added instance. In the example the <code>once(&#39;ping&#39;)</code>listener is removed:</p>
