I think the shown ability to splice to a unix socket may be misleading. 
Can someone offer some insight to my previous post (22nd April, "splice() 
on unix sockets")? Does splice to a unix socket actually result in zero 
copy?

  $ ./test_splice
  in\out  pipe    reg     chr     unix    tcp     udp
  pipe    no      yes     yes     yes     yes     yes
  reg     yes     no      no      no      no      no
  chr     no      no      no      no      no      no
  unix    no      no      no      no      no      no
  tcp     yes     no      no      no      no      no
  udp     no      no      no      no      no      no

Thanks
