Hmm. If you were managing your own pool then you could call close() on
the pool.

Arguably, if Tomcat creates an context level pool, Tomcat should close
it when the context stops but I don't think it does. That probably calls
for some testing to check behaviour and possibly an enhancement request.

Can you close the connections from the database management tools?
