No, because I was only researching the application in question.  Yes, I 
now know that it's possible to mount your nfs partitions so that this 
can't happen, but at the time I was discussing a possible way for a 
program to avoid it even if the partitions are hard mounted.  (What if 
you don't have control over the mounting, and your sysadmin insists on 
using hard mounts?)  Not, of course, because I expect it to be done but 
because I found the possibility interesting in and of itself.
