Some people have /usr/bin/python as a link to python3. The script is designed to work in either python2 or python3, but python3's subprocess model defaults to close_fds=True, which closes the jobserver fds and causes an error. Explicitly force close_fds=False to get identical behaviour on python2 and python3. Reported-by: Tharre <tharre3@gmail.com>
