I just did a comparison of the copying speed of shutil.copy against the
speed of a direct windows copy using os.system. I copied a file that
was 1083 KB.
I'm very interested to see that the shutil.copy copyfileobj
implementation of hacking through the file and writing a new one is
significantly faster... any clue as to why this is? I figure I'm
missing something here.
Does os.system launch a cmd shell every time?
