New submission from Serhiy Storchaka <storchaka+cpyt...@gmail.com>:
Dangling threads are reported when run test_socket tests which raise SkipTest
in setUp() in refleak mode.
$ ./python -m test -R 3:3 test_socket -m testBCM

test_socket failed (env changed)
== Tests result: SUCCESS ==
1 test altered the execution environment:
test_socket
Total duration: 655 ms
Tests result: SUCCESS
It happens because tearDown() is not called if setUp() raises any exception
(including SkipTest). If we want to execute some cleanup code it should be
registered with addCleanup().
