Add some comments?

Can you use TrivialURLRequestContextGetter?

[David Trainor- moved to gerrit, 2016/02/17 21:09:48]

Can't without dealing with annoying thread ownership issues :(.  The actual
underlying context isn't refcounted, but the getter is.  So in this case I want
the getter to build the context on the IO thread and to own the lifecycle :(.

+ public:
+  BlimpClientURLRequestContextGetter(
+      const scoped_refptr<base::SingleThreadTaskRunner>& io_loop_task_runner);
+
+  // net::URLRequestContextGetter implementation.
+  net::URLRequestContext* GetURLRequestContext() override;
+  scoped_refptr<base::SingleThreadTaskRunner> GetNetworkTaskRunner()
+      const override;
+
+ protected:
+  ~BlimpClientURLRequestContextGetter() override;
+
+ private:
+  scoped_refptr<base::SingleThreadTaskRunner> io_loop_task_runner_;
+
+  net::URLRequestContextBuilder builder_;
+  scoped_ptr<net::URLRequestContext> url_request_context_;
+
+  DISALLOW_COPY_AND_ASSIGN(BlimpClientURLRequestContextGetter);
