I am not sure whether this is expected behaviour from `synchronization` keyword.

Similar code in Java. It has settled on about 62M and didn't increase at all.

[code]
public class Main{
        private void other(){}

        public void close(){
                synchronized( this ){
                        other();
                }
        }

        public void hasData(){ System.out.println("Has Data"); }

        public static void main( String[] args ){
                for(long i=0; i < 250000000; ++i){
                        Main conn = new Main();

                        conn.hasData();

                        conn.close();

                        conn = null;
                }
        }
}
[/code]

But yes I would say, it is not intentional behaviour. It should use weak reference, so It would be possible for GC to collect it. Please

fill issue

And on 2.066.1 it works correctly, so it is a regression
