Per comment in RenderWidgetHelper::FromProcessHostID this needs to be called on
IO thread, while most (if not all) of public RenderProcessHostImpl methods are
supposed to be called on UI thread. Would be definitely good to comment about
that.. and probably it could also note that if the caller is on UI thread it can
directly call GetNextRoutingID().
