> Scheduling one process over another would be no more expensive than jumping from one green (userspace) thread to another on regular OSes, which would be a huge change compared to current OSes, but isn't quite a unikernel, at least under the provided definition. Sounds more or less like any embedded kernel that runs on an MMU-less cpu. Do unikernels handle interrupts? If so that means they can have preemptive threads, rather than green.
