+(*) Pickling, as well as changing threads, could be implemented by using
+a "soft" stack switching mode again.  We would get either "hard" or
+"soft" switches, similarly to Stackless Python 3rd version: you get a
+"hard" switch (like now) when the C stack contains non-trivial C frames
+to save, and a "soft" switch (like previously) when it contains only
+simple calls from Python to Python.  Soft-switched continulets would
+also consume a bit less RAM, at the possible expense of making the
+switch a bit slower (unsure about that; what is the Stackless Python
+experience?).
