How many working directories can be opened?  If it is 
limited, what happens after you've opened a file up,
got a working directory reference number to access
that file, and then you close that working directory.
It that reference number no longer valid.  If so, what
can you do if OpenWD returns too many working dirs?

I can't just go closing that last one I opened, it may 
have a file in it that I opened.
