Subject: [PATCH] test: fix test-debug-port-from-cmdline
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This test was failing because the spawned process was terminated before
anything could be done, by calling child.stdin.end. With this change,
the child's stdin is no longer closed. When the stdin is not a tty,
io.js waits for the whole input before starting, so the child must be
run with --interactive to process the command sent by the parent. The
child is killed explicitly by the parent before it exits.

This test was failing silently because the asserts were not called if
nothing was received from the child. This fix moves assertOutputLines to
always run on exit.
