This bug in bpo-33329:
https://bugs.python.org/issue33329was fixed for 3.6+, but it also affects 3.4 and 3.5. The bug is that with newer versions of glibc--which I'm pretty sure has shipped on all major Linux distros by now--the test suite may send signals that are invalid somehow. As a result the test suite... blocks forever? I think? Anyway the observed resulting behavior is that there are three regression tests in each branch that seemingly never complete. I started the 3.4 regression test suite /nine hours ago/ and it still claims to be running--and the 3.5 test suite isn't far behind. Technically, no, it's not a security bug. But I simply can't ship 3.4 and 3.5 in this sorry state.
Obviously it'd be best if the folks involved with the original PRs (Antoine?) took over.
Well, I don't know how to backport a PR to 3.4 or 3.5.
The patch changes < 10 lines in iterable_to_sigset in Modules/signalmodule.c. The relevant parts of the function in 3.4, 3.5, and pre-patch 3.6 appear to be the same, though with different line numbers. I have not used git cherrypick or python cherrypicker for months, but would expect them to do the merge.
