[issue20006] Sporadic failures of test_weakset

[Serhiy Storchaka]

New submission from Serhiy Storchaka:

test_weakset often fails on FreeBSD. Fo example see http://buildbot.python.org/all/builders/AMD64%20FreeBSD%2010.0%202.7/builds/285/steps/test/logs/stdio.

test test_weakset failed -- Traceback (most recent call last):
  File "/usr/home/buildbot/koobs-freebsd10/2.7.koobs-freebsd10/build/Lib/test/test_weakset.py", line 491, in test_weak_destroy_and_mutate_while_iterating
    self.assertTrue(u in s)
AssertionError: False is not true

Second run of this test is successful.
