commit 0102305e3573868b852faf5183451676beaedbe6

    Clean out tracking for blocks that are merged into other blocks
    
    The IO system in linux often merges blocks together to reduce the number of
    IO operations sent to IO devices. If nothing is done the tracking for
    merged IO operations can fill up the associative arrays, causing the script
    to fail.  This problem was reported in rhbz743591. This commit resolves
    this problem.
