That's not a bug, but a deliberate choice. In Python 3, file descriptors are no longer inherited by default by child processes (fork+exec). Jelle is right, it was changed by my PEP 446. You must use pass_fds=[fd] parameter of subprocess. Or at least, make the file descriptor inheritable (worse solution).
