You really should find some place in the code to use this, even if it's for something basic. It's frowned upon to add APIs and then not actually use them anywhere.
Also, big props for writing a test case!</pre>

<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">I think that here and everywhere else you use ao2_ref or __ao2_ref(), you should replace it with __ao2_ref_debug(). This way, you can pass along the file, line, and function that will in 99% of cases be more helpful for someone trying to debug refcount issues. At least do this when REF_DEBUG is defined.</pre>

It is anticipated that the Asterisk 11 Configuration Management project could use these new API calls to replace an active configuration parameter object with an updated configuration parameter object.
With these new API calls, the global object could be replaced, removed, or referenced without the risk of someone using a stale global object pointer.</pre>
