Paul, thanks, that did the trick.  Interestingly enough, it was FAR slower 
than single threading it.  As others mentioned, because I am writing to the 
same disk at the same time, I lose any potential advantages of 
multithreading.  At least I was able to get it to work for the sake of 
comparison/education.
Single threaded: 33 seconds
Multi threaded: 57 seconds
