In my testing of sparse files, I found that the extra disc usage did not
appear to be reported in Explorer File Properties "Size on Disc", but was
visible in the overall Disc Properties, by looking at the change in free
space.

I'm not saying blocks are definitely being wasted in the above case - just
that the data above does not conclusively prove that there is no waste.

I have no time right now, but I will try a test using df to investigate this
later.
