[SQLObject] Using a persistant connection

[Nick <ni...@dd...>]

If I want to keep a persistant db connection but not cache, I can see
how I can do this by saying:

class._connection.cache = CacheSet()

but I'm not sure if mucking with the internals like that is the right
way to go.  Is there some other way to handle this that I'm not seeing? 
If not, should there be?
