Note that in this case, the sizes are also the same -- apparently, the
program in question just does stuff to regions inside the file,
without changing the file's size. (I think that's a common technique
for dealing with really big files: you just do seeks-and-writes for as
long as you can, and only after space usage gets really inefficient do
you do an expensive resizing.)
