This patch exposes a new read-only property of multiprocessing.Process objects, named "sentinel".
As the doc indicates, this is a file descriptor undex Unix, and a handle under Windows. Both are suitable for flexible polling/waiting with the appropriate OS primitives. They become ready when the process has ended.
Under Unix, this also replaces the repeated polling in _Popen.wait() (called from Process.join()) with a regular select() call, making it friendlier with CPU low-power states.

This is necessary for issue9205.
