  SVN rev 186493 on 2008-12-25 11:32:38Z by rwatson
  
  Following the recent security advisory, add a comment describing our
  invariants and approach for protocol switch methods in protsw_init(),
  and also some KASSERT's for non-domain init entries in protocol
  switch tables: pru_abort and pru_send must both be implemented.
  
  For now, leave those assertions #if 0'd, since there are a few
  protocols that violate them in non-harmful ways.  Whether or not we
  should enforce pru_abort being implemented for non-stream protocols
  is an interesting question: currently abort is only invoked on stream
  sockets in situations where un-accepted sockets must be abruptly
  closed (i.e., close() on a listen socket with pending connections),
  but in principle it is useful for datagram sockets and most datagram
  socket types implement it.
