I wonder if this has the same cause as the problem reported here:

Mark, can you check that?
Hmm, the correlation between failing Python versions and patch placements is
troubling. I've reproduced the OP's findings and will dig further.

3.5 has not your patch for asyncio, as I am not updating it.
all the others have it. It will be nice to solve this problem and avoid the freeze
that your patch solved.
It turns out a small adjustment to the existing patch fixes this latest issue and
shouldn't affect the situations reported in the original bug report that provoked
the patch in the first place.
Line 11 of the patch 3.6.12-socketmodule.patch has:
............return -1;
using dots to denote spaces because this mailer might deformat this email. If
that patch line is replaced with:
............/* ignore error returns */;
we have a patch that solves the latest issue as well as the original issue.
That revised patch should also apply to 3.7 and 3.8 without problems.
Thanks & Regards,
..mark
