Works the same as a LimitCache with two very important differences:

1) data is stored in an out of memory database using the shelve module.

2) all keys are converted to strings using the str() function. MAKE
   SURE this conversion preserves the integrity of the hash. The str() function
   MUST be completely cannononical for this db to work correctly.
