> This build was only triggered by one changeset 0b99d7043a99: "Issue #23694: Enhance _Py_open(), it now raises exceptions". I was reproduce to issue on a buildbot and I got access to the buildbot. Using gdb, I saw that a process was stuck in _close_open_fds_safe(). The problem is that this function is called after fork() to run a child process. It's not safe to play with the GIL here. This bug is the regression which makes some buildbots to hang. I fixed the bug in the changeset 2e1234208bab. I keep the issue open a few days to check if buildbots are repaired or not.
