-//  ExternalTabProxy is a mediator between ChromeProxy (which runs mostly in the
-//  background IPC-channel thread) and the UI object (ActiveX, ActiveDocument).
-//  The lifetime of ExternalTabProxy is determined by the UI object.
-//
-//  When ExternalTabProxy dies:
-//  1. Remove itself as a ChromeProxyDelegate. This blocks until _Disconnected()
-//     is received.
-//  2. Kills all posted tasks to the UI thread.
-//  3. Stop all network requests
-//  => It does not have to (and should not) be a refcount-ed object.
-
-// Non-public inheritance is not allowed by the style-guide.
