Quick fix for memory/module refcount leak.
Reference count of listener instance never reaches 0.
Start/stop of ulogd2 is enough to trigger this bug!
Now, refcounting there looks very fishy in particular this code:
if (!try_module_get(THIS_MODULE)) {
...
and creation of listener instance with refcount 2,
so it may very well be ripped and redone. :-)
