Subject: Re: [path][rfc] add PR_DETACH prctl command [3/3]

The attached patch implements the PR_DETACH prctl
command. It detaches the entire process group from
its parent, allowing the parent to still read the detach
code with normal wait(). If the process then exits, the
notification of the new parent is delayed till the old parent
does either wait() to read the detach code, or exits.
