// 2. The RenderFrame can be unloaded. In this case, the browser sends a
// UnfreezableFrameMsg_Unload for the RenderFrame to replace itself with a
// RenderFrameProxy and release its associated resources.
// |lifecycle_state_| is advanced to LifeCycleState::kRunningUnloadHandlers
// to track that this IPC is in flight.
// 3. The RenderFrame can be detached, as part of removing a subtree (due to
// navigation, unload, or DOM mutation). In this case, the browser sends
// a UnfreezableFrameMsg_Delete for the RenderFrame to detach itself and
// release its associated resources. If the subframe contains an unload
// handler, |lifecycle_state_| is advanced to
// LifeCycleState::kRunningUnloadHandlers to track that the detach is in
// progress; otherwise, it is advanced directly to
// LifeCycleState::kReadyToBeDeleted.
//
// The browser side gives the renderer a small timeout to finish processing
// unload / detach messages. When the timeout expires, the RFH will be
// removed regardless of whether or not the renderer acknowledged that it
// completed the work, to avoid indefinitely leaking browser-side state. To
// avoid leaks, ~RenderFrameHostImpl still validates that the appropriate
// cleanup IPC was sent to the renderer, by checking IsPendingDeletion().
//
// TODO(dcheng): Due to how frame detach is signalled today, there are some
// bugs in this area. In particular, subtree detach is reported from the
// bottom up, so the replicated UnfreezableFrameMsg_Delete messages actually
// operate on a node-by-node basis rather than detaching an entire subtree at
// once...
//
// Note that this logic is fairly subtle. It needs to include all subframes
// and all speculative frames, but it should exclude case #1 (a main
// RenderFrame owned by the RenderView). It can't simply:
// - check |frame_tree_node_->render_manager()->speculative_frame_host()| for
// equality against |this|. The speculative frame host is unset before the
// speculative frame host is destroyed, so this condition would never be
// matched for a speculative RFH that needs to be destroyed.
// - check |IsCurrent()|, because the RenderFrames in an InterstitialPageImpl
// are never considered current.
//
// Directly comparing against |RenderViewHostImpl::GetMainFrame()| still has
// one additional subtlety though: |GetMainFrame()| can sometimes return a
// speculative RFH! For subframes, this obviously does not matter: a subframe
// will always pass the condition |render_view_host_->GetMainFrame() != this|.
// However, it turns out that a speculative main frame being deleted will
// *always* pass this condition as well: a speculative RFH being deleted will
// *always* first be unassociated from its corresponding RFHM. Thus, it
// follows that |GetMainFrame()| will never return the speculative main frame
// being deleted, since it must have already been unset.
