<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">You probably could just move the module ref passed the check for feature_limits being allocated successfully and ref bump the module once you know the destructor will be called on error.</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 had it there initially. I did it this way because this code is in the module in question and the ref needs to be bumped ASAP and allocations may take awhile. Module ref changes really should happen while no code in the module is running. It just has a tendency to be difficult to do sometimes.</pre>

* Fixed memory leak in off nominal paths of bridge_builtin_set_limits().
* Fixed off nominal path in ast_bridge_features_limits_construct() freeing unallocated memory if it was not called by bridge_builtin_set_limits().
* Made bridge_builtin_interval_features.so unloadable.
* Simplified parking's use of its duration interval hook.
* Made BridgeWait S option not depend upon another module being loaded.</pre>
