The bpo-31151 (socketserver.ForkingMixIn.server_close() leaks zombie processes) was fixed in the master branch, but 2.7 and 3.6 branches were not changed.
I proposed to modify test_socketserver to explicitly waits until child processes complete. See attached PR.
Example of leaked child processes the on "x86 Gentoo Refleaks 3.6" buildbot:
