as long as newblahstuff != blahstuff it should be ok, because if 
newblahstuff points to the same memory as blahstuff, and you free what is 
at blahstuff, newblahstuff points at freed memory (this is bad)

only the data in blahstuff is free'd, (but the data pointed to by a 
pointer in blahstuff is still there) hope this didn't confuse you more :)
