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.
