Yes indeed that is the case. Hurd does so by passing the memory buffer 
pointer to those functions but I don't know where NetBSD would do the 
equivalent. Perhaps that's in a NetBSD libc or in NetBSD kernel space, 
but wherever it is, the same restriction on the memory for that pointer 
must also apply. Possibly I need to reword that part to make sure 
there's no misunderstanding.
