I don't see one offhand, but I wouldn't want to assume there aren't
any; there are socket types that don't need connect() - UDP, raw
sockets, and special cases like routing sockets.  I'm not convinced
they need this kind of socket cloning, but I'm not convinced they
don't, either, and I can easily imagine it being useful for UDP.

I still think the domain/type/protocol should be inherited from the
template socket rather than passed in.
