I think that it is time to re-think how the routing socket works. Having
each program and the kernel deal with sending and receing all versions of
all messages is wasteful and painful to maintain. In the short term we
should fix things to use a message filter to indicate interest on the
message types they are interested, but the question is what to do in
the long term...
