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]
