[issue27068] Add a detach() method to subprocess.Popen

[Martin Panter]

Martin Panter added the comment:

The user can access pipes and close them directly, or keep their own reference. I don’t think detach() should touch pipes, and __exit__() should probably continue to close them. Maybe call the method detach_pid() if that makes it clearer that pipes are unaffected.

For the Windows process handle, I suggest detach() should close it. I believe this would make Windows work like Unix when you set SIGCHLD to automatically reap children.
