I haven't checked closely now but if you just touch the FPU in the
handler thread and then transmit it, it should work so that any is
getting an FPU state. And you probably do not want to have it back then.
On the other side, in your execution model, I think you don't even need
to forbit doing any L4 call, I should just work.
