Right, that's longer, and only tests one interaction.  The isolation spec I posted upthread tests multiple interactions
betweenthe session which uses cursors and the system going read-only.  Whether the session using a cursor gets a FATAL,
justan ERROR, or neither depends on where it is in the process of opening, using, closing and committing.  I think
that'sinteresting.  If the implementation of the ALTER SESSION READ ONLY feature were to change in such a way as, for
example,to make the attempt to open the cursor be a FATAL error, you'd see a change in the test output.
