Can someone shed any > more light on this? I have talked with peoples from DEC Moscow about DigitalUnix (former OSF/1). They said that the last version of it has monolithic kernel on top of Mach. They said also that DEC did this for both performance and stability reasons. So it looks like the microkernel is a bad idea yet. Although, I know that peoples in DEC Moscow indeed have very little information from DEC about anything except prices :-) and their words may be completely wrong. -SB
