Part of that is because things are somewhat convoluted :-).

I've applied some of your suggestions, as well as a bit more
noise-trimming and clarification, to:

  http://www.watson.org/~robert/freebsd/20040303-sockets.ps

Hopefully this is somewhat of an improvement.  I also added some more of
the socketvar.h macros to my "hinted" edges -- apparently prcc doesn't
really do much with our large macros, and so I was missing some edges.
