That's less not needing a debugger by design, more how challenging it is to debug an operating system.

Those last two (speaker and clock) yes, but otherwise no. Linus Torvalds really doesn't like using a debugger and he'd rather you didn't use one either. His words:

Wow. Lets add some sleep in the compiler also so people will think harder about their code before compiling?

[tropo]

I think that is excessive, but it isn't entirely wrong.

I worked at a place with builds that took over 8 hours. We sure would think hard about our code.

He's not wrong.

I still maintain that debuggers are a design smell.
