The requested flushes from inside the namespace and for namespace exit really should just flush the routes for that namespace. However for general route caching and expiry I don't see the point of making the code per namespace, and my gut feel is that is likely to reduce average case performance at the cost of better isolation between namespaces. Denis did I read the patches right and you are making all route cache flushes per namespace? Including the periodic expiry?
