The easy way is to make sure that the file you are dealing with is
larger than your physical RAM, if you are dealing with it sequentially.

You can ensure that the cache is flushed by unmounting the filesystem,
so if you remount before reading and after writing you know that the
cache is flushed.

 It's not a recursive function except in the sense that it calls itself.
