[boost] Cleaning delete

Hi All,

        What do you think about optional set of new/delete operators which 
clean memory in delete() by filling it with zeros. I mean an 
implementation with the standard syntax, so that any old program using 
the standard new/delete can be linked with the modified version of 
new/delete without any change in the program text and even without its 
recompilation. I have never heard whether this simple idea was 
implemented anywhere. In fact, these operators are useful for sequre 
aplications, which are not expected to leave significant information in 
the dynamic memory. This is also useful for debug of any program that 
uses direct allocations with raw pointers, the style which it known to 
be prone to errors. The use of already deleted information is more 
likely to be detected, if this information is physically deleted. The 
cleaning new/delete operators might be made very simple (almost trivial, 
except exception safety) and perhaps completely portable. Does this idea 
look useful?
