[J-core] Fuscia/littlekernel

[Rob Landley]

Any opinions on Google's new Fuscia RTOS?

It's loosely based on the "littlekernel" project:

  https://fuchsia.googlesource.com/magenta/+/master/docs/mg_and_lk.md

But they're implementing a userspace:

Overall it seems a bit misguided (A microkernel _again_? All system
calls nonblocking?) but the concrete isn't dry on this one, and I am
sort of curious what it would take to port it to j-core and get
musl+toybox to run on it. (So far they're doing x86-64, but littlekernel
itself supported arm, so j3 presumably wouldn't be a big leap...)
