- I don't know the exact definition of "microkernel", but I think any kernel
- will only be real-time if it is intended to be from the start.
- Let's see, the original VRTX 68000 kernel (c.1984) occupied 4K. Is that
- micro enough? I think the original Unix, too, had the intention of a small
- and efficient kernel, without going so far as coining a new buzzword.
- It was never meant to be real-time, though.
