Issue was caused by recent image cache rewrite and root of the issue goes to the fact that blender player doesn't initialize cache limiter and it uses 32meg of memory only. This leads to infinite image loading/freeing. For now disabled cache limiter in game engine, this brings back old behavior. In theory we might be smarter here, but better caching policy is to be discussed.
