This will help a lot.  We want to throw memcache in front of the queries
and having it all centralized like that will make it trivial (or at
least, a lot easier).  I might be able to help change all the old
database calls starting later today, I'll let you know.  Is there a
preferred method you want me to follow to verify I don't break anything?
I imagine that re-running all the tests after each change should cover
it, but if there's more to it, let me know.
