The point of this system is to isolate the implementer from the
implementation details of the original, so they can't copy those
details. They are supposed to only be given an interface to implement,
which they may do differently (if that's possible while still
implementing the required interface). It doesn't work if the
implementer is told the implementation details, so when doing this you
have to be careful about the information you give.

I can't explain why the relay call out from wininet to winsock is too
much information in this case, but it's been a general policy that we
don't look at the calls native makes. (I also learned that policy the
hard way, unfortunately.)
