[issue18571] Implementation of the PEP 446: non-inheritable file descriptors

[STINNER Victor]

STINNER Victor added the comment:

+    if (make_inheritable(py_fds_to_keep) < 0)
+        goto error;
+    /* errpipe_write is part of py_fds_to_keep. It must be closed at
+       exec(), but kept open in the child process until exec() is called. */
+    if (_Py_set_inheritable((int)errpipe_write, 0, NULL) < 0)
+        goto error;

make_inheritable() should ignore errpipe_write, instead of changing twice the inheritable flag of errpipe_write.
