Perhaps 'dns is the wrong symbol to use for :nowait, since it isn't
really about DNS, but getting a fully asynchronous connection.  That is,
:nowait t gives us a fully set up socket, really (seen from the
application point of view).  Perhaps :nowait 'immediate or something
would make more sense than :nowait 'dns, which is, after all, just an
implementation detail.

Yes.
