I just realized this may be a problem for the use case of RemoteTestServer. Make
sure people using it are OK with this.

   RemoteTestServer(Type type,
                    const std::string& host,
                    const base::FilePath& document_root);
 
   // Initialize a TestServer with a specific set of SSLOptions.
-  // |document_root| must be a relative path under the root tree.
+  // |document_root| must be an absolute path.
   RemoteTestServer(Type type,
                    const SSLOptions& ssl_options,
                    const base::FilePath& document_root);
