When I create two instances of a Qthread derived class and run both threads.
Which area/space do they share now?

I know, that using static makes it possible. But without static variables?
Just the pure QThread-class with "normal" private variables.

I know its a bit stupid but,..all my tests showed my that they dont share anything.

Example1:
I counted on both instances an int var (private). No problem.

Example2:
I declared a var in run() and done sth with it on both threads...no problem.

So where do they share sth?
