The pragmatic solution here is to not worry about it and let it be the 
user's problem if he does something stupid.

It's OS specific how to get at this information. On Linux, for example 
you can call the `fuser` program (if installed; on Ubuntu it's in the 
psmisc package). But this will only tell you if the same user has the 
file open (or if you're root).
