From TFA:

Curious what benefits this would have vs the usual virtualization? VM’s are the typical strategy for subdividing machines with high core counts into multiple kernels, and seems to work well enough?

Think it can be used for lockstep computing.
Also seems to be a way to bring microkernel benefit to Linux. Isolate system services.
