The draft standard indicates that deleting a null pointer will have no
effect.  Even if the _Annotated C++ Reference Manual_ reads, "The effect of
applying delete to a pointer not obtained from the new operator without a
placement specification is undefined and usually harmful.  Deleting a point
with the value zero, however, is guaranteed to be harmless" (p. 63).
