So I can say that in linux 'thread' == 'process'?
Is kernel routine 'kthread' creating a process? I'm just thinking on this subject: if to create 'real threads' - will it increase performance? Should I ever think in this way? When I say 'real thread' - I mean the thread that doen't switch context when it's starting to run.
