Don't generalize. The 4G/4G kernel, for instance, doesn't have this
property. Who knows what else will come up. Anyway, two memcpy are
slower than one.
But this does not allow more than one context to be set at a time, like
the current implementation does. Ie, the current implementation allow you

Of course it does. It just requires an appropriate union element.
