What you are experiencing is the Android built-in task killer, OOM=out of memory and LMK=low memory killer, which close processes when in need of RAM. Your launcher is an application like any other and it runs in RAM. Should the system decide it's in need of RAM, if you're playing an intensive game, or you're switching between dozens of open apps, the launcher can get killed off just like any other app or process. When you see the loading screen, it means the launcher was killed and is starting up again.
There's really no helping it, though personally it never happened to me with this 2GB phone, but you can try and exit apps using the BACK button. Only use the home button to close an app if you're coming back to that app soon so you want it to be kept in RAM. Otherwise, close apps with the back button. The processor of the phone is fast enough to load any app into RAM almost instantly.
