Hooks sound nice but they have some problems:

  *  they make it much more difficult to use efficient data structures
     and algorithms

  *  they require much more work for the modification.

I am interested to keep very near to the current efficient
"cPickleCache" implementation -- both to keep the result
efficient and to keep the workload for me low.

I am happy if someone else presses ahead and comes
with some very flexible and reasonably efficient implementation.
