CCTextureCache::reloadAllTextures() block my game

Hi
I have ported our app from IOS to android, and everything works great! thanks cocos2dx.

One issue:
when the game is running and I push the menu hardware button, the app goes in the background. When I click the app, then 5-10 sec are passing before the game is back in business. This is because of the TextureCache running reloadAllTextures(). I need to handle this someway - maybe just showing a message to the user the he/she should wait while loading. Is it possible to reloadTextures asynchronously? or what would you suggest?

Thanks.
