Not sure it makes sense to use an enumerated type for |dscp|, given that the
supplied values will typically be ints, e.g. as obtained from
http://tools.ietf.org/html/draft-dhesikan-tsvwg-rtcweb-qos-02. If you made it an
int, you could pass values from DiffServCodePoint, but also allow explicit DSCP
settings to be passed without casting.

Got a third and a fourth opinion, I think people generally prefer the enum.

+
   // Must be called before the socket is destroyed. The delegate may
   // not be called after |closed_task| is executed.
   void Close();
