Description

A NSE could be freed by the application on multiple events.
However there are certain cases when multiple events are emitted which will result in a use-after-free when called in the wrong order.

Unsure if it needs the usage of use_count.
At least recursions of free_nsvcs(), free_nsvc() and free_nse() must be prevented.
