per-cpu tcbinfo[]s aren't ready for prime time yet.  The tcbinfo is assigned
at tcp_attach time, but there is insufficient information available at this
time to select the hash table and the wrong one gets assigned N-1 out of N
times on MP systems (N = number of cpus), causing outgoing tcp connections
to fail.

An an option, TCP_DISTRIBUTED_TCBINFO, so MP-safe tcbinfo distribution can
continue to be developed without impacting users.
