I think the way I phrased the question above makes the problem sound 
harder than it is...
I am unittesting a C extension.  The extension opens files using 
open().  I want to make sure that the extension closes all the files it 
opens (when errors occur or whatever).

So I figured getting a count of open file descriptors before the 
extension code is called and after it is finished would enable me to do 
this.
