"setup.py doesn't use multiprocessing. multiprocessing is super complex. Would it be possible to write a reproducer which doesn't use multiprocessing?" But the problem is with the handling of fork() by Python modules, and specifically with multi-threaded fork()s. Without multiple processes there is no issue. And setup.py does use use multiple processes via a thread pool, where each thread calls fork(), if it detects that "make" was invoked with the parallel (-j) option. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue39763> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
