Comment:

 On reflection I don't believe this can be fixed. os.path.exists() only
 fails "if permission is not granted to execute os.stat() on the requested
 file", but to check for read permissions we also need os.stat().

 On my platform (Ubuntu) os.path.exists() and os.path.stat() works as
 expected. If folks have some uber locked down system that breaks os.stat()
 then they're asking for the confusion.
