As a destructor in a RAII_VAR macro, you have to assume that you may be passed NULL. In bridgewait_exec, that will occur if your allocation routine fails - in which case this will be called and passed NULL. You'll pass NULL to holding_bridge_wrapper_pull_if_allowed, which will at a minimum FRACK when you pass NULL to ao2_ref.</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;">Previously the holding bridge used for bridgewait was a single bridge that once created would stick around until the application was unloaded.
Now things are a little more complicated. Each holding bridge has a name and will be destroyed when it is empty. Since it's theoretically possible to have channels enter a holding bridge without going through the bridge wait application, it isn't always possible to deliberately control when the bridge will be destroyed, so the bridge can effectively be abandoned and set to be destroyed once it empties out.</pre>
