     \todo We should probably remove BufferingPolicy from the

-    it ??)

     \todo Do we want to support separate read and write policies. This

+    \idea Creating a new Socket will create 4 (!) new instances (The
+       handle, the body, the policy and the protocol) of which 3
+       (argh) (body, policy and protocol) live on the heap. This is
+       expensive. We should convert all the policy classes to
+       singletons and assign the same instance to all socket bodies
+       with the same policy. This would reduce the number of heap
+       allocations per socket handle to two.
