What if someone runs an ASM program that totally takes control of the entire calc, though, even disabling interrupts? Isn't ASM that powerful or will your program detect what code is about to be ran and prevents its execution like an antivirus?
A malicious program could easily do whatever it wants to do, since it has direct access to the processor. Preventing such programs would be very hard.

Last I heard, KOS supports programs that disallow threading. Most games would probably want to do this for speed reasons.

Ah, thanks for clarifying. :) What if someone runs an ASM program that totally takes control of the entire calc, though, even disabling interrupts? Isn't ASM that powerful or will your program detect what code is about to be ran and prevents its execution like an antivirus?
I can't do this.  Any program would be able to hijack your calculator under any OS.

This is correct.

How will it handle the thread stopping process?  EG. if one thread asks to take over, what will the other threads do?

The user will be provided with a confirmation dialog, where they have to agree or disagree to allow it.  They can still switch threads at this time, so they can go save their work and such.  Then, all other threads will be shut down, and memory will be reorganized.  Multithreading will be disabled and control returned to the calling thread.

What about custom interrupt routines?

I know he'll be able to launch the version by 1 January for a fact.  I'm working on USB routines, so I know those won't really be in KOS dev version. I'm not sure, but I'm pretty sure he'll get it done.

Will that release be publicly available or only for certain people?

I think (from what I heard) that it will be available for everyone, but only developers will be interested in it.

Right. Well, I will probably still check it out anyway, just to see how it looks like on-calc. :P

I'm not sure if it will be bootable. I'm guessing not, since I'm pretty sure he's releasing the kernel.

Yes, it's gonna be a very basic version, so that programmers can start developping their programmes. So that when it is released, it doesn't take much time to start publishing programs.
