This was pushed earlier, nice!

Was this done already or not?

This is not done yet. And I'd really like this to go in before the next
release. Would it be possible to push this out? I see recent commit now even
taking into account the nanosecond field of mtime... this two second delay is
pretty much harmful. If FAT is of concern still, it should have additional code
to 'touch' the file until the stat() returned time is changed, or something
similar.

Please push them out :)
