[TIMOB-14389] Android Maps API v2 leaks huge amounts of memory

My App uses google map v2. It has about 50 Annotations and 66 Routes on it, when I first time open the map in a modal window, everything works smoothly, however, every time when I close the map window, then open it, the app becomes slower and slower, it eventually crashes with out of memory exception. The situation is worse in android 2.3 devices, much better on 4.0+ devices, So I googled it and found this link https://code.google.com/p/gmaps-api-issues/issues/detail?id=4766, so other people have the similar issues. It seems google has fixed the leak, can we incorporate the changes to the v2 map module?
