    sys/netinet          tcp_input.c tcp_subr.c tcp_usrreq.c 
  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.
