Victor will more than likely be able to give a more definitive reason on why those 2 commits did = not get backported to python3.8 since Victor is the author of those commits :) Anyways, I have the upstream python bugs for those 2 commits: https://github.com/python/cpython/commit/9ad58acbe8b90b4d0f2d2e139e38bb5aa3= 2b7fb6 links to https://bugs.python.org/issue19466 https://github.com/python/cpython/commit/4d96b4635aeff1b8ad41d41422ce808ce0= b971c8 links to https://bugs.python.org/issue39511 Without those 2 commits, if you take the python script I posted earlier and simply run a while true loop in the shell repeatedly calling it, you will notice that it will eventually hang indefinitely. With the 2 commits, the w= hile true loop runs forever as expected. --=20 You are receiving this mail because: You are the assignee for the bug.=
