--- Comment #71 from slw@zxy.spb.ru ---
(In reply to Michael Tuexen from comment #70)

RFC: "An acknowledgment by TCP does not guarantee that the data has been
  delivered to the end user, but only that the receiving TCP has taken
  the responsibility to do so."

Nothing about failed delivered to application. This information is unavaila=
ble
on TCP level.
