The CLOSE callback should happen to any connection that got as far as
being ESTABLISHED... it's deallocated during the close flow that
produces that callback.
For client connections it's possible to pass in your own user_data
object and a second "opaque_user_data". But for server, the wsi are
generated when clients connect at their own whim, so the auto-allocated
user data is convenient.
