abs() is a gcc builtin function, but the kernel is compiled
with the -fno-builtin option (it wasn't when I added abs()
to zs.c).

Leo, can you add an inline function to zs.c:
static inline int32_t abs(int32_t x)
{
	return x < 0 ? -x : x;
}

Yes, especially the console driver. :-(
I suspect that integrating the VM/buffer subsystems
would give an overall performance increase.

One of the things you can easily do for yourself is
mounting an mfs on /tmp.
