This is just a little bit tricky. os.remove (on FreeBSD 5-STABLE,
anyway) throws an OSError exception if it doesn't have permission to
remove the file, *or* if the file doesn't exist. You have to examine
the exception for it's value, which is the result of a strerror
call. I believe that the result of strerror is platform dependent.
