(Re)Actors
TBH, I am a big fan of actor- and reactor-like programming patterns (also known as Finite State Machines. While you’re not strictly required to use reactors and might be able to get away without them – they DO provide several very substantial benefits.

While L3 kernel can STILL run on MMU-less RAM-constrained MCUs, it provides responsiveness which is comparable to that of multi-stack kernels.
Another Quote:
multi-coring is essentially a special case of balancing shared-nothing nodes

Quote:
low-end versions of the new OS should be lean enough to run on a ~$1 MCU (these days ~=4K RAM, 32K ROM)
Another Quote:
