Re: NPTL

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.
