Intermittent "permission denied" errors when using os.rename and a recently deleted path??

I'm actually running both... but I would think that once os.remove
returns that the file is actually gone from the hdd.  Why would either
application be blocking access to a non-existent file?

Of course, my thinking is obviously wrong since I do get the permission
problem... I will definitely try disabling those.  Now if only I could
reproducably repeat it to make testing easier. :(

Another thing is that I certainly do want the code to work in the
presence of such tools.
