 * ``VersionedFile.clear_cache`` and ``enable_cache`` are deprecated.
   These methods added significant complexity to the ``VersionedFile``
   implementation, but were only used for optimising fetches from knits - 
   which can be done from outside the knit layer, or via a caching
   decorator. As knits are not the default format, the complexity is no
   longer worth paying. (Robert Collins)
