instance constructor sets stationary member, thread safe?

i am re-factoring formula am wondering a lock instance constructor.

public category myclass {

    private stationary int32 opposing = 0;
    private int32 mycount;

    open myclass() {

        lock(this) {
            counter++;
            mycount = counter;
        }
    }
}

please confirm

1. instance constructors thread-safe.


2. the close matter prevents opening formula block, stationary 'counter' member.

if vigilant uncanny programmer have any instance know the 'count', i synchronize opening 'counter' member pledge another thread isn't new'ing myclass changing count before sets the count?

fyi - category singleton. instances contingency simply wakeful number.
