Yeap, I know there are two sides of the discussion but if one takes
the position that hiding such global debug info is more harmful, it's
only crazier to hide such information from each individual users of
the said global facility.  So, let's just forget about information
leak via freeing or not freeing here.  It's the wrong battle field.

Thanks.
