Summary: System.out.print Flood Makes DrJava Hang

Initial Comment:
When printing very long lines without line breaks, DrJava slows down and becomes unresponsive. It basically hangs. This isn't the case when the same amount of information is printed, but with line breaks inserted.

This program is bad:

public class FloodDrJava {
    public static void main(String[] args) {
        for(int i=0; i<10000; ++i) {
            System.out.print("Hello "+i+" ");
        }
    }
}

This program is not so bad:

public class FloodDrJava {
    public static void main(String[] args) {
        for(int i=0; i<10000; ++i) {
            System.out.println("Hello "+i+" ");
        }
    }
}

It seems like it's appending to long lines that's killing the performance.
