I'm sure this one can be gotten rid of in a future CL.  In fact, all o f them in
dart:io can be, I think.

They sure can.

+      absolute = absolute.join(new _Path.raw(u.path));
       path = absolute.canonicalize().toString();
     }
     replaceComponents(scheme: scheme, host: host, port: port, path: path);
