Why don't you use a collection of file organized as stack in one directory
or in many directories if your underlying file system cannot effectively
support many files in one directory. If your pickles are small (much less
than block size of the file system) you can keep several of them in one
file about the size of the block size. Since the files will be small you can
simply rewrite them competely each time you need change them.
