+1. My instinct is to agree with Phil on this one. The driver for a lot
of this work is making DBCP perform better in concurrent use scenarios
(where Tomcat's jdbc-pool currently beats it hands down performance
wise) and I'd rather trade some maintenance overhead for a simpler (and
better performing) implementation.

That said, without some hard performance numbers this is just guess work
and my instinct could be completely wrong.
