I need a class that creates a dictionary file that lives on disk
<p>I want to create a very very large dictionary, and I'd like to store it on disk so as not to kill my memory. Basically, my needs are a cross between cPickle and the dict class, in that it's a class that Python treats like a dictionary, but happens to live on the disk. </p>

<p>My first thought was to create some sort of wrapper around a simple MySQL table, but I have to store types in the entries of the structure that MySQL can't even hope to support out of the box. </p>
