<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">A process_config lock is needed to serialize loading/reloading configuration requests.</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;">Are you sure? The serialization happens at the apply_config stage in this example. Multiple simultaneous reloads will create new objects and will be swapped atomically.</pre>

<pre style="margin-left: 1em; 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 serialization using the global_config_transaction lock happens too late in the config loading. I also had other issues with the use of that lock and the data organization as pointed out above.</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 patch adds config parsing to app_skel to serve as an example of how to properly write config handling using the ao2 global object API for thread-safe reloads. I also made a couple of whitespace changes even though they technically should have gone in a separate patch, but they didn't get in the way of seeing what changed, etc.</pre>
