Right. I looked into FBSD code a little.
(I am not a kernel GURU, just looking)
Puzzles me how this could be ported into some "middle layer",
not being part of the "no more monolithic" kernel.

The middle layer code would have to mask signals coming from
the kernel (sounds not too hard) and switch contexts in an MP_SAFE
manner. (locking?) Is there some sort of preemption needed? Can this fit
into "middle layer"?

Just asking. Trying to understand DFly concepts.
