implement a more scalable jdbc datasource pool in AbstractJdbc4PoolingDataSource. The jdbc4 specific subclass should allow me to use use the concurrency api in 1.5+, For that to work ant could switch to the correct AbstractJdbc4PoolingDataSource at compile time (due to PGPoolingDataSource extends it).
Is this something of interest ?
I would also like to make the current implementation in AbstractJdbc23PoolingDataSource threadsafe.
