  Modified files:
    sys/kern             uipc_syscalls.c 
  Log:
  Fix an inconsistency in socket option propagation on accept(). Propagate
  the SS_NBIO flag from the parent socket to the child socket during an
  accept() operation.
  
  The file descriptor O_NONBLOCK flag would have been propagated already
  by the fflag assignment, and therefore would have been inconsistent
  with the underlying socket's so_state member.
  
  This makes accept() more closely adhere to the API contract we effectively
  outline in the manual page. Note also that Linux continues to differ here;
  O_NONBLOCK is not propagated. The other BSDs do propagate the flag, as
  does Solaris. The Single UNIX Specification does not offer specific
  advice on this issue.
