Ok, I reproduced the issue on David's buildbot. A (child) process was stuck in _Py_open(), function called from _close_open_fds_safe() which is called to run a child process. Calling _Py_open() is not safe here because the GIL may or may not be held. After fork, the status of the GIL is unclear. I fixed the issue by replacing _Py_open() with _Py_open_noraise(), this version doesn't use the GIL (it doesn't release the GIL to call open() and it doesn't raise an exception). https://hg.python.org/cpython/rev/2e1234208bab Thanks David for the buildbot.
