Changeset <https://trac.webkit.org/changeset/223149/> (bug #178102) inadvertently changed the copying semantics in WebProcessProxy such that we no longer ref WebPageProxy objects before calling their functionality. In bug #181771 we fixed this inadvertent change made in WebProcessProxy::didClose(). There are more places that r223149 touched that we need to fix up. It is not safe to loop over WebPageProxy objects calling functionality that may call a delegate because the delegate can do anything including deallocating itself and other WebPageProxy objects.
