how would one go about doing this? i learned in my TP3/6 days to use fillchar on 
everything to ensure that it was filled with 0x00... especially my data files... 
when looking at them with a hex editor, my OCD would hit strongly because the 
data file was "not clean and holding only my data"...

i don't know how one would go about cleaning released memory as someone else 
asked about (eg: extending an array or string or etc)... once the memory is 
released, it is no longer accessible, right?
