Just wanted to note: Mac OS X does *not* use this kind of OS. Its
kernel is monolithic, in that all the pieces live together in the same
address space, and communicate via procedure calls, not messages. Mach
messaging can be, and sometimes is, used between processes, and between
process and kernel [in some cases; BSD system calls are not turned into
messages].
