Hi -

Please consider these two ditties.  They make the test case conclude
successfully & reliably on my fedora-22 rawhide vm.

    qa/518: stretch timing to run more reliably
    
    This test case involves a race between pmie running rules a certain
    number of times, and a separate task waiting (by time) to match the
    results via /usr/bin/pcp.  It was observed as flakey, not always
    winning the race.  This version stretches the pmie time and fine-tunes
    the waiting interval to give the race a larger (multi-second) window
    for success.

    qa/518:
    
    It was observed that the $sudo pmie invocation didn't always
    receive the closing signal at this test case, leading it to
    hang.  Now we kill it harder, both by pid and later by name.
