I'm able to reproduce the issue in a reliable way using attached bisect10 file and the command:

$ ./python -m test test_multiprocessing_fork --timeout=40 -v --matchfile=bisect10
(...)
test_fork (test.test_multiprocessing_fork.WithProcessesTestQueue) ... ok
test_get (test.test_multiprocessing_fork.WithProcessesTestQueue) ... 
Timeout (0:00:40)!

bisect10 contains 68 tests.
