* Fixed TCPEndpoint::Listen() never setting the backlog on its socket, causing 

only a single pending connection to be accepted at once.
* Fixed discarding endpoints that still had a parent, but were closed before
  they could be accepted (or even established). Previously, these were never
  deleted, slowly filling up the socket's backlog.
