Hey Victor. Github thinks you might be a good reviewer, so I've requested your review. Please take a look, or re-assign to someone else (Łukasz maybe), or suggest another avenue. Thanks.

LGTM.

Displaying test method docstrings caused me many practical issues when analyzing buildbot results. For example, it's harder to apply a regular expression to convert a test output to a list of test method which have been executed. I need to do that to re-run the same test methods, usually to bisect a reference leak.

@pablogsal: do you want to also have a look into this regrtest output change?

[pablogsal]

LGTM

Thanks for the PR @jaraco !

⚠️⚠️⚠️ Buildbot failure ⚠️⚠️⚠️

Hi! The buildbot AMD64 RHEL7 LTO 3.x has failed when building commit a941e59.

What do you need to do:

1. Don't panic.

Test failures are "no space left on device". Seems to be a buildbot issue and not related to the patch.
