One of the points with garbage collection is that the objects are not cleaned up immediately they get unused. The garbage collector can determine for iteself when it's most convenient to do collections.

It's normal for a garbage collected system to leave some unused objects in the heap, as long as there is plenty of memory to use. A computer doesn't run any faster from having a lot of unused memory.
