It does.  However there is no way to ensure that everyone seeing the file
will have a consistent view of it.  This is especially the case when they
are on different machines.

However there can even be consistency issues when all client processes are
on the same machine.  This is because the client operating system should be
segmenting its cache by user - ie if my user and your user map the same
network file they should not share the client cache - as that is wonderful
way of doing cache poisoning attacks.
