* at the end of the loop, which is propably the most common case for
* releaseObjects.
*
* If a garbage collector is added in the future, it will tell the GC that now
* is a good time to clean up, as this is often used after a lot of objects
* have been added to the pool that should be released before the next iteration
* of a loop, which adds objects again. Thus, it is usually a clean up call.
