<p>This function is used when the null-ness of a completion callback is used as a signal for whether a completion callback has been registered. In this case, after the execution of the callback, it should be cleared. However, this introduces a conflict if the completion callback wants to schedule more work that involves the same completion callback again (for example, when reading data from an URLLoader, one would typically queue up another read callback). As a result, this function clears the pointer before the provided callback is executed. </p>

<p>There is no practical use of this function for third party modules. Its existence is because of some internal use cases inside Chrome.</p>
<p>Since your module runs in a separate process, there's no need to free allocated memory. There is also no need to free any resources since all of resources associated with an instance will be force-freed when that instance is deleted.</p>
<p><b>Note:</b> This function will always be skipped on untrusted (Native Client) implementations. This function may be skipped on trusted implementations in certain circumstances when Chrome does "fast shutdown" of a web page. </p>
