    Indeed. I misread the !capable(CAP_KILL) as "I am not allowed to kill the
    other guy", which clearly you are when you just forked it.

    This looks like a bug to me. If you own the process, you can send it any
    signal you want, so you should be allowed to sign it up for SIGURG/SIGIO via
    F_SETOWN.
