test/jdk/java/lang/ThreadLocal/MemoryLeak.java introduced in https://bugs.openjdk.org/browse/JDK-4414045 loops 1.1 million times. When it was created, it was probably correct, but with modern heap sizes my thinking is that there will never be a shortage of memory and if we would leak, we would not notice it as we have enough heap size to leak far more than 1.1 million objects. I think the test ought to be started with a limited heap size, and maybe more iterations

Maybe something like:
```
/*
 * @test
 * @bug 4414045
 * @summary Tests to see that memory leak no longer exists.
 * @run main/othervm -Xmx60m MemoryLeak
 */

public class MemoryLeak {
    public static void main(String[] args) {
        for (int i = 0; i < 30_000_000; i++) {
            ThreadLocal t = new ThreadLocal();
            t.set(new Object());
            t.set(null);
        }
    }
}
```
