 // MULTI-THREADING NOTICE:
 //   URLRequest is designed to have all consumers on a single thread, and so no
 //   attempt is made to support ProtocolFactory or Interceptor instances being
 //   registered/unregistered or in any way poked on multiple threads.  However,
 //   we do support checking for supported schemes FROM ANY THREAD (i.e., it is
 //   safe to call SupportsScheme on any thread).
