I'm not sure if NFS insulates you from it, but my understanding of the
difference between IN_MODIFY and IN_CLOSE_WRITE is that an IN_MODIFY event
is emitted for each and every write that hits the filesystem. So let's say a
large file is being copied between systems, and you're watching that file on
the destination system. You'll see numerous IN_MODIFY events. If you copied
the file based on one of them, you wouldn't get the entire file.

That's the beauty of IN_CLOSE_WRITE. You know the file that has been
modified, is now closed.

I think I've managed to answer my own question elsewhere in this thread as
to why I was seeing the behaviour that I was seeing.
