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]. Regards, Justin -- Justin C.
