If the socket is already closed when writeHead is called, we're supposed
to silently ignore it instead of throwing an error . The close event is
supposed to be emitted on the next tick. Now, I think there are also
cases where we do not emit the close event which is similarly bad.
### How did you verify your code works?
Need to go through the node http server tests and see if any new ones
pass. Also maybe some will fail on this PR, let's see.
