#210 debugging non-closed connections

[Bill Burke]

Non-closed connections will be released and removed from
pool on a transaction commit.
Also, a stack trace will be printed of where the non-closed
connection was created. This behavior is configurable so
you MUST turn it on(see config below).

Only use with ReleaseOnCommit!! If a release

you will get a stack trace of where the

NOT released. -->
