* <li> delegates JDBC <tt>Connection</tt> management to the <tt>ConnectionProvider</tt>
* <li>factory for instances of <tt>SessionImpl</tt>
* </ul>
* This class must appear immutable to clients, even if it does all kinds of caching

* safe, but also highly concurrent. Synchronization must be used extremely sparingly.
