The subprocess module's close_fds=True behavior is suboptimal. It gets the maximum fd number and calls close() on each possible fd in the child process. When you're running on large systems configured for 1million+ file descriptor limits per process.... This makes launching a subprocess uber painful. I'm in the middle of some posix subprocess fixing, i'll add this to my todo list and fix it up.
