The live kernel debugging sounds... scary. Can you explain how would

Yes, it is scary. No, the system doesn't stop -- it's just a racy way
to read and write kernel memory. I don't think it's used often but I've
been told that sometimes it can be very helpful in debugging annoying
non-crash bugs, especially if they're hard to reproduce.
Interesting.
So how would this be represented in lldb? Would there be any threads,
registers? Just a process with a bunch of modules ?
