Since you wrote your own ConnectionManager, you have the opportunity to
control everything about the JDBC objects handed-out to the application.
Why not use that to your advantage and do all this housekeeping within
either the ConnectionManager class (say, to create your UserInfo
objects) or in wrappers around object such as Connection to do this in
the close() method or others?
