Specify permutations for isolation tests with "invalid" permutations.

This is a necessary prerequisite for forthcoming changes to allow deadlock
scenarios to be tested by the isolation tester.  It is also a good idea on
general principle, since these scenarios add no useful test coverage not
provided by other scenarios, but do to take time to execute.
