I've always thought a neat hack in operating systems (file systems, to be
pedantic) would be for them to test a (small) file, when it is closed after
writes have taken place, to see whether anything has _actually_ been
changed (so it would have to do a read-compare-write for every write, yes),
and not update the m-time if nothing has. These things keep me awake at
night, you know. Maybe I need help!!! ;-)
