Duh. I've never seen one of those before, but I guess it had to happen eventually.

I don't know how well they are documented, but with Mach sources lying around it shouldn't be impossible to find out what -33 does. We could probably try to implement even the Mach system calls, but I have to agree with you that maybe it would be a good idea to just try to avoid using the DU native threads implementation. That may or may not be possible (even with shared libraries any library-exposed datastructures etc global knowledge can make it fairly hard to make linuxthreads be binary compatible with the DU pthreads).
Does anybody know more about Mach system calls or the DU threading model?
