I'm sorry, but the Un*x-world I've known has always been multi-processor, and the last decade it started turning into massively-multi-processor, so I don't quite follow you there

Desktop PCs, those used to be typically uni-processor, but you would be hard pressed to find un*x-based workstation without at least two CPUs (or at least additional socket for one).

When is intra-process communications based on threads manditory.? I was taught that with multi-CPU machines, threads are disadvantegous (because all of synchronisation necessary, when you move you process around, for example to another CPU, you need to keep it's memory ( cache ) synced, instead of keeping in sync only the data that the worker actually IS working on).

When did IPC::SysV, IPC or IPC::Msg drop out of favor?
