174 <p><code>removeListener()
</code> will remove, at most, one instance of a listener from the
175 listener array. If any single listener has been added multiple times to the
176 listener array for the specified
<code>eventName
</code>, then
<code>removeListener()
</code> must be
177 called multiple times to remove each instance.
</p>
178 <p>Once an event is emitted, all listeners attached to it at the
179 time 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
180 will not remove them from
<code>emit()
</code> in progress. Subsequent events behave as expected.

184 <p>Because listeners are managed using an internal array, calling this will
185 change the position indices of any listener registered
<em>after
</em> the listener
186 being removed. This will not impact the order in which listeners are called,
187 but it means that any copies of the listener array as returned by
188 the
<code>emitter.listeners()
</code> method will need to be recreated.
</p>
189 <p>When a single function has been added as a handler multiple times for a single
190 event (as in the example below),
<code>removeListener()
</code> will remove the most
191 recently added instance. In the example the
