In this chapter, we'll look at the most distinctive feature of Neutrino,
message passing.
Message passing lies at the heart of the operating system's
microkernel architecture, giving the OS its modularity.
A small microkernel and message passing
One of the principal advantages of Neutrino is that it's scalable. By "scalable" I mean that it can be tailored to work on tiny embedded boxes with tight memory constraints, right up to large networks of
multiprocessor SMP boxes with almost unlimited memory.
