More background. People may be wondering why this is even an issue for
FreeBSD as a router.
The answer: the imo_membership array contains members which exist as
separate entries for each ifnet in the system, and the system where this was
observed to be a problem had a number of ifnet interfaces which was larger
than IP_MAX_MEMBERSHIPS (20).
I'm loosely of the opinion that the membership array should be variable
length, and that we should default it to 20, but have a significantly larger
maximum. It's not horribly efficient, but also wouldn't be so particularly
terrible either.
