The property that one person changing a shared file can munge it up for
anyone else using it is still a large part of the CMS philosophy.  The
only way around it is for the person with write permission on the file
to be nice about the way he/she updates it.  It is ok to create new
files on the disk, and a simple RENAME does not hurt the other
person (who doesn't see either the new file or the new name).  So
you make your update to a new file, quickly rename the old one to
something like BLAH OLD1 and quickly rename the new one.  This is
how we update the system disks.  Great, huh?  You can imagine
what happens to a disk that has two people writing on it...
