<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">This can still be problematic, since the unsubscribe can happen within the topic's dtor. The ao2_ref will erroneously increment the topic's refcount back to 1, and the sub will have a bad pointer to the topic, which it will try to re-delete when its refcount goes to 0.</pre>

<pre style="margin: 0; padding: 0; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">This review covers several items involved in the transition of MWI from the event system to Stasis:
* Creation of cache dump capability (necessary for pollmailboxes in app_voicemail)
* Addition of subscription change notices (necessary for pollmailboxes in app_voicemail)
* Update of the Stasis unit tests to cover those new items
* Ability to set a server EID on messages</pre>
