Mike Bayer c12854807d - The per-dialect cache used by TypeEngine to cache
dialect-specific types is now a WeakKeyDictionary.
This to prevent dialect objects from
being referenced forever for an application that
creates an arbitrarily large number of engines
or dialects.   There is a small performance penalty
which will be resolved in 0.6.  [ticket:1299]
