Sure, there's no particular reason that subclassing ConnectionPool
can't be done, but the only difference is that you're using methods
like "self.runQuery" instead of "self.db.runQuery" (after doing
"self.db = ConnectionPool(etc)". I probably wouldn't subclass unless I
actually wanted to override one of the methods in ConnectionPool with
a modified implementation and then use it in the same place that a
regular ConnectionPool is expected.
