:The modification/accessing to the udbinfo is protected by two mechanism:
:1) netisr barrier, which prevents code running in netisr from
:accessing udbinfo when the modification is going to happen
:2) serializer, which prevents code not running in netisr (e.g. sysctl,
:interface detaching) from accessing udbinfo when the modification is
:going to happen
:
:1) makes the udp input/output path lock free.

UDP-related kqueue issues which might be fixed by this.
