Hi Pydeas,

I encountered exceptions like

  File "c:\python27\lib\site-packages\filecache-0.67-py2.7.egg\filecache\__init__.py", line 82, in function_with_cache
    rv = function.__db[key]
  File "c:\python27\lib\shelve.py", line 122, in __getitem__
    value = Unpickler(f).load()
cPickle.UnpicklingError: could not find MARK


With my filecache module which I have a feeling are related to database failures upon abrupt termination of the process.

If I write the class SqliteShelf, would it be of use to anyone? Would it be a viable patch for shelve.py?

Note that I don't mean to affect the shelve.py "open" function, just to add a reliable alternative class.
