+// The Context class is RAII-style class for managing IO operations within the
+// Cache.
+//
+// When a Context is created it performs the complicated steps necessary to
+// initialize the QuotaManager.  Action objects dispatched on the Context are
+// delayed until this initialization is complete.  They are then allow to
+// execute on any specified thread.  Once all references to the Context are
+// gone, then the steps necessary to release the QuotaManager are performed.
+// After initialization the Context holds a self reference, so it will stay
+// alive until one of three conditions occur:
+//
+//  1) The Manager will call Context::AllowToClose() when all of the actors
+//     have removed themselves as listener.  This means an idle context with
+//     no active DOM objects will close gracefully.
+//  2) The QuotaManager aborts all operations so it can delete the files.
+//     In this case the QuotaManager calls Client::AbortOperations() which
+//     in turn cancels all existing Action objects and then marks the Manager
+//     as invalid.
+//  3) Browser shutdown occurs and the Manager calls Context::CancelAll().
+//
+// In either case, though, the Action objects must be destroyed first to
+// allow the Context to be destroyed.
+//
+// While the Context performs operations asynchronously on threads, all of
+// methods in its public interface must be called on the same thread
+// originally used to create the Context.
+//
+// As an invariant, all Context objects must be destroyed before permitting
+// the "profile-before-change" shutdown event to complete.  This is ensured

+// running in the parent process.
+//
+// There should be exactly one Manager object for each origin or app using the
+// Cache API.  This uniqueness is defined by the ManagerId equality operator.
+// The uniqueness is enforced by the Manager GetOrCreate() factory method.
+//
+// The life cycle of Manager objects is somewhat complex.  While code may
+// hold a strong reference to the Manager, it will invalidate itself once it
+// believes it has become completely idle.  This is currently determined when
+// all of the following conditions occur:
+//
+//  1) There are no more Manager::Listener objects registered with the Manager
+//     by performing a Cache or Storage operation.
+//  2) There are no more CacheId references noted via Manager::AddRefCacheId().
+//  3) There are no more BodyId references noted via Manager::AddRefBodyId().
+//
+// In order to keep your Manager alive you should perform an operation to set
+// a Listener, call AddRefCacheId(), or call AddRefBodyId().
+//
+// Even once a Manager becomes invalid, however, it may still continue to
+// exist.  This is allowed so that any in-progress Actions can gracefully
+// complete.
+//
+// As an invariant, all Manager objects must cease all IO before shutdown.  This
+// is enforced by the Manager::Factory.  If content still holds references to
+// Cache DOM objects during shutdown, then all operations will begin rejecting.
