Currently, the only thing that the kernel knows about environment
variables (or at least "most of the kernel," i'm not going to say that
i've looked in all of the machine-dependent nooks and crannies) is

	There's this extra argument to execve() which specifies
	a program's environment, and which should be plopped into
	the newly-created address space.

It's not clear that changing that would be a real feature.
