Do you need |is_open|, or can you just use database_dispatcher_host_?

It proceeds the CloseAll() which can trigger side-effects like unblocking
the connection queue. I'll add a comment.

+
   // Note that we explicitly separate CloseAll() from destruction of the
   // DatabaseDispatcherHost, since CloseAll() can invoke callbacks which need to
   // be dispatched through database_dispatcher_host_.
