please try to register for traps/infrms with empty Oid- and
TargetCollections.
Depending on the passed Collections CNotifyEvent::notify_filter() will
return false and the received trap is ignored.

No, it will be startet just once.

This is desired behaviour: If the thread is running, the start function
returns true, as it is (still) running.
