Here is a rewrite of multiprocessing.{PipeConnection,Connection} in pure Python, for ease of maintenance and improvement.

Nothing jumps out at me at initial review; I've asked other contributors/interested parties to take a look too. Thanks a ton Antoine for doing this work |

The patch slows down Pipe() a bit, by the way. On my machine, each message sent and received has an additional 10µs overhead. See attached benchmark script. |

This is great! I always wondered if it was really necessary to use C for this. 10µs overhead should be worth it ;) I've read the patch, but not carefully. So far nothing jumps at me either. Cheers! |

Updated patch, fixing a sporadic failure in test_spawn_close. |
