This is quite intentional, and I have no intention of changing it.
Initializing the memory is inefficient if it will be written before being
read anyway. Besides, if it *does* need to be initialized, zero might not
always be the appropriate initialization value to use.

FYI, the same thing must be done for blocks allocated with HeapAlloc. In
fact, Fargo *uses* HeapAlloc to allocate BSS blocks.
