[Python-Dev] Newish test failures

[Tim Peters]

Seeing three seemingly related test failures today, on CVS HEAD:

test_csv
test test_csv failed -- errors occurred; run in verbose mode for details
test_descr
test test_descr crashed -- exceptions.AttributeError: attribute
'__dict__' of 'type' objects is not writable
test_file
test test_file crashed -- exceptions.AttributeError: attribute
'closed' of 'file' objects is not writable
3 tests failed:
    test_csv test_descr test_file

Drilling into test_csv:
