Does this mean that a thread can be made "un-killable"? As in, some rampant thread hogging too many resources or something. In other words, is there a "force-kill" or some kind of shutoff or warning if resources get out of hand?

You can always manually kill an unruly thread, don't worry.

Question about the update: If a thread in particular happened to freeze, for example a buggy program ending up in an endless loop, would it still be possible to switch to another thread to be able to kill the one that crashed, or will we still need to use the old way and pull a battery?

That's one of the great things about KnightOS.  You would be able to leave that program and kill the thread, thus saving yourself the effort of a battery pull (and any of the data you have unsaved in other programs).

I mean, not even WFRNG needs battery pulls! Cast a curse on ti-os!

Well, it is admitedly hard to prevent battery pulls, TI just isn't as 1337 as us and we should not fault them for it.

The axe version did :P It crashed my nspire bad enough to need a battery pull. It crashed outside the emu.

I would assume processes could still crash the calc if they're naughty and have too much power, though, right?

So, could a ROM of KnightOS be legally distributed? I mean, the ROM's mainly used for the OS, and since this is going to be a free OS we should be able to distribute the ROM as well, right? Or, are there other copyrighted parts of the ROM that remain?

It's going to be source code, that's all I know, so I think ROM's could be distributed :D

Probably a stupid question, but what if it corrupts all the RAM stuff used by other threads? Or is that impossible?

Yeah, you're only protected from infinite loops.
RAM corruption is impossible to prevent; the nature of the z80 processor is what causes that.

Oh, okay, I wasn't sure because I didn't know if having to request for 768 bytes at a time prevented this or something.

An infinite loop with interrupts disabled is impossible to break out of, though. Disabling interrupts will disable threading automatically, anyway

It would, because the ROM would not contain any code from TI.

Aren't the boot pages and such unable to be replaced?
