That gives me a) no buffer, who's pointer is b) not initialized to null.
I want instead a defined pointer, to a valid array, that is initialized to  
zero.

Anyway, I think the flaw in my proposal is the use of a GC. Since we don't  
get the memory directly from the operating system, but from a memory pool  
in the GC, it is generally 'recycled' and already used memory. It has to  
be zeroed out manually, unless there was a way to tell the OS to rebind  
some virtual memory addresses in our program to this magic 'zero page'.
