aha, I just noticed that os.popen doesn't give any return code.  Hmm,  
tricky.

My first two thoughts are to either look at the existence of stderr as  
indication of success or failure (which runs into problems with verbose  
programs spewing junk onto stderr), or just ignore retcodes for the windows  
version and always assume that the previous command worked.  Neither is  
immediately appealing, but I've only thought about it for two minutes and  
haven't tried any experiments yet, so that's no reason to give up.
