"Real Multitasking", and all that. Calling WaitNextEvent between sending/receiving every message is just too slow for some classes of distributed applications. Remember that Mach is a new OS which has lots of very interesting features. You probably won't ever find these features on SysV- or BSD-based Unixes. Read comp.os.mach for details. < As to the "suppression of information" and "stranglehold on Mach" < I can only suggest you try to control your paranoia.

Without that information, I'll stick to the paranoia theory. :-) Actually, what I'd like to do is take the Mach 3.0 kernel that's freely available, combine it with the Mach 2.5 Unix server and the [object or, preferably, source] code to make it run on the Mac, and hack away. This seems to be possible with some other Mach versions, so I honestly don't see what the problem is. Someone "in the know" please enlighten me... -- Matthias Urlichs -- urlichs@smurf.sub.org -- urlichs@smurf.ira.uka.de /(o\ Humboldtstrasse 7 - 7500 Karlsruhe 1 - FRG -- +49+721+621127(0700-2330) \o)/
