Over on bug report https://issues.asterisk.org/view.php?id=18637 jpeeler has
uploaded a patch bug16837.patch which
gets rid of the zombie channels but adds a lot of locking and unlocking.

Based on that patch https://issues.asterisk.org/view.php?id=18684 could probably
be closed out because these
zombies disappear with bug16837.patch
