This looks like an API breaking change, it could break people's tests.

e = e.exceptions[0]
self.assertEqual(str(e), 'CleanUpExc (2 sub-exceptions)')
self.assertEqual(str(e.exceptions[0]), 'CleanUpExc1')
self.assertEqual(str(e.exceptions[1]), 'CleanUpExc2')

Normally exceptions are not raised in test cleanup code, so I do not think this change will break people's tests. It will change the error report to better if there were multiple errors.

e = e.exceptions[0]
self.assertEqual(str(e), 'CleanUpExc (2 sub-exceptions)')
self.assertEqual(str(e.exceptions[0]), 'CleanUpExc1')
self.assertEqual(str(e.exceptions[1]), 'CleanUpExc2')
