I tried using Schevo and it didn't affect memory use or performance,
at least for my particular application. I tested it the following way:

- "easy_install -b BUILD_DIR -Z schevo"
- Change all "durus" imports to "schevo.store"
- Disable Durus in easy_install.pth and verify it's not importable
- Run the import and my sample search.

I noticed Schevo doesn't have a PersistentSet class.  This was added
to Durus recently. In my case I wasn't using it anymore so I deleted
the import.
