Leaks happen only when both testDoctestFile and testDoctestSuite are run.
Run with Python 3.4.2 and 3.4.1 with same result.
I have extracted those two tests into `leak.py` (attached).

Note that when I remove support.modules_cleanup(*modules_before) from leak.py valgrind reports no leaks (in original test_zipimport those are run in setUp and tearDown).
Output of
