NFS is only guaranteed to flush the file to disk when you do the
close(). Your program will just result in a lot of cached writes right
up until the moment it exits...

...and no - we do not update timestamps on the client side when we cache
the write, 'cos NFS does not provide any device for ensuring that clocks
on client and server are synchronized.
