Google Maps waking phone

I did have a play around with Latitude, which is what I assume it is that's waking the phone, but I've since disabled it.

However, I've recently been monitoring the phone using logcat and have noticed the following every now and again...

I/ActivityManager( 1111): Start proc com.google.android.apps.maps:BackgroundFriendService for service com.google.android.apps.maps/com.google.googlenav.friend.android.BackgroundFriendService: pid=5914 uid=10014 gids={3003}

D/LocationManager( 5914): Constructor: service = android.location.ILocationManager$Stub$Proxy@43615588

I/ActivityManager( 1111): Stopping service: com.google.android.apps.maps/com.google.googlenav.friend.android.BackgroundFriendService


Is there a way to disable this properly? Neither of the location services are enabled.
