/**
 * Tests the Session read refactoring / reading through the write connection
 * properly feature.
 * On three tier, when UnitOfWork is in transaction, must not only use the
 * write/dirty connection, but also must not put objects read with that dirty
 * connection into the shared cache.
 * <p>
 * UnitOfWork needed to be able to execute queries directly, and to build
 * working copy clones directly from a database row, as opposed to from an
 * original already placed in the shared cache.
 * <p>
 * This series of tests is on a ClientSession, and all UnitOfWorks begin
 * transaction early.  Tests verify that no objects are placed in the UnitOfWork
 * cache until commit time, and that merging where originals may or may not exist
 * in the shared cache works.
