New submission from Jack O'Connor: Setting stdin=PIPE and then calling communicate(b"") should close the child's stdin immediately, similar to stdin=DEVNULL. Instead, communicate() treats b"" like None and leaves the child's stdin open, which makes the child hang forever if it tries to read anything.
