You know, that probably *would* work. That's a neat idea. I'm a 
little wary of including something like that in a high-use OS library 
though; it seems like too much of a hack. Plus, it looks like you 
can call rstat with a pathname to find out what the stream type is. 
It'd probably be safer to go with that.
