commit 66119f1fe341d34bec41dd5e81e18c759d2f9ad5
Author: Ken Raffenetti <raffenet at mcs.anl.gov>
Date:   Wed Jul 31 12:51:11 2013 -0500

    Add FT test with communication. Tweak other FT tests.
    
    Adds an FT test that attempts communication without touching a
    failed process. Other changes are to use SIGKILL to simulate failures
    and also to flush all output to stdout.
