Google Maps Android API v2 SupportMapFragment memory leak

Using 2 simple activities. First Activity which only holds
a button to start the 2nd Activity which holds the
map:

Main
Activity:

public class
            MainActivity extends Activity {

@Override
protected void
            onCreate(Bundle savedInstanceState) {

            super.onCreate(savedInstanceState);

            setContentView(R.layout.activity_main);
}


public
            void goToMap(View view){ //This is just the onClick method for the button

            Intent intent=new Intent( this, BigMapTest.class);

            startActivity(intent);
}

The
map activity:

public class
            BigMapTest extends FragmentActivity {
SupportMapFragment
            mapFragment;

GoogleMap
            map;

@Override
protected void onCreate(Bundle arg0)
            {
 // TODO Auto-generated method stub

            super.onCreate(arg0);


            setContentView(R.layout.travel_diary_big_map);


            mapFragment=(SupportMapFragment)
            getSupportFragmentManager().findFragmentById(R.id.big_map);


            map=mapFragment.getMap();

}

The
XML Layout for the map
activity:

            xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
            >



            android:id="@+id/big_map"
 android:layout_width="fill_parent"

            android:layout_height="fill_parent"

            class="com.google.android.gms.maps.SupportMapFragment" 

            />

Now
when I run this code, pressing the button to move to the Activity with the map, and
pressing back to get to the first activity...then repeating the process, I can see the
heap increasing in size each time, until it reaches it's limits and then it starts
clamping. If you mess around a bit more with map(i.e. zooming) I can get an OOM
Exception at this point.

Any
