May be better to call it NullSocketServer

Done.

That doesn't look right. I think that message queue without a socket server
should still work as expected. This class should use talk_base::Event. Wait()
should just call Event::Wait.

[Ronghua Wu (Left Chromium), 2012/02/28 17:50:47]

Done.

This should signal event that Wait() waits on.

Why not set this in the constructor? That way you wouldn't need that field.

[Ronghua Wu (Left Chromium), 2012/02/28 17:50:47]

If a socket server is passed from external, the MessageQueue won't take the
ownership of it.

[Sergey Ulanov, 2012/02/28 21:54:01]

In that case it's better to rename owned_ss_ (to be consistent with other code)
and set ss_ in the constructor.

   ss_->SetMessageQueue(this);
