We still use the Geronimo connection manager implementation, and  it 
still enlists/delists transactions as usual.  However, instead of 
pooling in Geronimo, whenever a connection is requested we get it from 
the OracleDataSource (backed by the Oracle pooling) and when a 
ManagedConnection is returned we destroy it, returning it to the 
OracleDataSource and presumably the Oracle pool.  I think the 
geronimo-ra.xml in the oracle adapter is not actually set up to enable 
Oracle datasource pooling, and we haven't really tested how well this
