Two additional regression tests for problems exposed by the 69740
patches. They tickle a different path than the test HJ already checked
in. Obviously the idea is to have these in place so that when we attack
69740 again, we don't regress these issues.
Installed on the trunk after verifying they PASS on the trunk.
