Just one more caveat, which might not apply in this case but a general advice for #popen and the likes: buffers between processes are limited. If you handle everything single threaded there is potential for deadlock. This will always happen if you send more data longer than the buffer size to the pipe and the other process will also send more than buffer size data. Then both are blocked on IO.
