// level of indirection provided by the AwContentsContainer abstraction.

// Object lifetime:
// For most purposes the java and native objects can be considered to have
// 1:1 lifetime and relationship. The exception is the java instance that
// hosts a popup will be rebound to a second native instance (carrying the
// popup content) and discard the 'default' native instance it made on
// construction. A native instance is only bound to at most one Java peer over
// its entire lifetime - see Init() and SetPendingWebContentsForPopup() for the
// construction points, and SetJavaPeers() where these paths join.
