most importantly, using the mode in the second argument of 2 argument open is right out.
Why? Does the code run faster with the 3 argument open than tha 2 argument open?

    The reason is mainly security, redirection coupled with pathnames can produce nasty effects at unexpected filenames. Using the 3 argument open to separate the mode from the path can prevent regrets.
