Well, let me think through what the wiki might say:

1. Download ZODB and patch it with poll-invalidation-1-zodb-3-8-0.patch
2. Install ZODB.
3. Get the relstorage package into your Python path somehow.
4. When creating the DB object, base it on a RelStorage instance instead 
of a FileStorage instance.

Step 1 is ugly, but it will get a lot better once the patch is 
integrated.  Step 3 is incomplete, but I guess putting relstorage in the 
Python package index will solve that.  Step 4 would be much better with 
an example.

Packing speed still disappoints me a bit.  I recently rewrote the pack 
algorithm for the 3rd time and it's still not as fast as I expect.  I 
need to figure out why.
