One way is via command line:

	gcc -Wl,-u,__use_dev_zero ...

Or, in main,

	__use_dev_zero();

I think very few programs actually need /dev/zero; dd is the only one
(aside from programs that mmap() it for shared memory, which we don't
support (yet?)) that I can think of that really benefits from it.

I guess it depends on how big the handler is, and if we want to carry
that kind of load in *every* program, and how big such a load can get
as we add more and more handlers.

I would think that making it the default would be wrong in general.
