from a speed standpoint, i think the 2-socketed approach is a little
better because you can pre-allocate them, and no further action is
needed at runtime.  so, faster at the expense of a some extra fd's.

sizeof(struct sockaddr_in) i believe.  i guess this value would be
different for ipv6 though.  currently in the code we use getaddrinfo's
results for the first batch of sockets.  the nice thing about that is
iirc the info passed back is compatible with ipv6 as well (the length is
a field in the results), so i guess that'd be another argument for the 2
sockets approach.
