It must.  If transactions are on, any pooling mechanism needs to continue to
use that connection for the client unti the transaction is done. (Most require
the client to either tell the pool manager the connection is no longer need,
via a close() call, or a pool-manager specific call, precisely because the
client needs it to complete the transaction.

My feeling is that if this is a problem, then this method call may need to be
limited to the transaction context, but I hope that this is not the case.
Most pool managers (and I'm only speaking about Java here) require some
activity on the client to give up the connection, either directly or
indirectly.
