get rid off the MAP_ONCE flag is MemoryHeapBase (as well as it's functionality), this feature should not be used anymore. the software renderer was incorrectly using the default ctor which set MAP_ONCE, causing the leak. the software renderer itself is incorrectly used while coming back from sleep.
