You could make it just a submodule in the test package.

./python -m test.bisect -R 3:3 testos I like the idea :-) I proposed a PR which was approved by Yury Selivanov, and so I just merged it! It means that you can now play with "./python -m test.bisect" in the master branch. Enjoy ;-) Example: ./python -m test.bisect -R 3:3 testmultiprocessingforkserver This command should give you the name of the two failing test methods which are the last known reference leaks! => http://bugs.python.org/issue30775 This specific bisection is very slow since running the 286 tests of testmultiprocessingforkserver using -R 3:3 takes longer than 3 minutes on my laptop! And the answer is already know, see the bpo ;-) FYI, apart of the bpo-30775, all other reference leaks now seem to be fixed on 2.7, 3.5, 3.6 and master branches! Tested on Windows and Linux. Victor
