[issue2223] regrtest.py -R not working

[Alexander Belopolsky]

Alexander Belopolsky added the comment:

test_collections fails (with -R :: only).  Does not look like something
related to the recent changes, rather test is not happy about being
repeated.

$ ./python Lib/test/regrtest.py -R ::  test_collections 
test_collections
beginning 9 repetitions
123456789
test test_collections failed -- Traceback (most recent call last):
  File "Lib/doctest.py", line 2131, in runTest
    raise self.failureException(self.format_failure(new.getvalue()))
AssertionError: Failed doctest test for collections.namedtuple
  File "Lib/collections.py", line 13, in namedtuple
