I suppose it's not the same what I'm asking for, isn't it?
Beside of this, 'sleep' introduced in 2.3, and not backported to my 2.2;)
Anyway, 'reject_unauth_pipelining' definitely not the same...
Let's imagine that little more thoughtful. When the server response
"220 bla-bla" code it falls into mandatory sleep stage, but server must
be able to flush the data from the network and detects TCP reset state
while it "sleeps", that's the goal/difference.
