Ok ten minutes later, after ton of garbage collection message it  
suddenly returned a mass of output.
So, suddenly it makes sense, its getting all the directories then  
outputting the information
so because there are a ton of directories under that one... gc gets  
called over and over and it
takes a long time to process...

Sorry, I shouldn't have assumed after just a minute that it wasnt  
going to return anything and that I still had it wrong...
