ignoring all synchronization problems you could also do it
via "static thread& thread::current()" which is much more
clear, IMHO:

class foo
{
public:
   foo() : owner( thread::current() ) { }
   bool current_thread_is_owner() { return thread::current() == owner; }
private:
   thread& owner;
};

foo * instance;

void thrd1()
{
   instance = new foo;
}

void thrd2()
{
   if (foo->current_thread_is_owner())
      do_something();
}
