I thought shared is only for whole of the object.
     auto thr = new DerivedThread();
Here, "thr" is not shared but it's member thr.count is shared?
But if it's not shared, thr object referred by main thread and
"this" reference of DerivedThread.run() are different?
What happen if there are both shared and unshared member exists?

class DerivedThread : Thread {
     shared int count = 0;
     int foo = 0;
}

Umm. I can't imagine what's the memory layout of this object.
