Result of testing on zero-granularity blocks, where the prog size and read size equals the block size. This represents SD cards and other traditional forms of block storage where we don't really get a benefit from the metadata logging. Unfortunately, since updates in both are tested by the same script, we can't really use simple bash commands. Added a more complex script to simulate corruption. Fortunately this should be more robust than the previous solutions. The main fixes were around corner cases where the commit logic fell apart when it didn't have room to complete commits, but these were fixable in the current design.
