> A PoolableConnection can know when it is "broken". (When a fatal SQLException is
> thrown.) A SQLException is considered fatal when it includes an error code from
> a configurable list of broken connection indicators.
> The attached patch is a partial implementation for review 
> (not all Delegating* methods are covered)
> Summary:
> Add a list of indicators that (when found in an SQLException) mark a Connection
> as "broken". Broken Connections will be destroyed and not returned to the pool.
> if (!isBroken()) {
>     _pool.returnObject(this);
> } else {
>     _pool.invalidateObject(this);
> }
