Long living objects lengthen the trace time which is a critical phase of the
garbage collection process. However, it is possible to recognize "object clusters",
i.e., groups of long living objects having approximately the same lifetime and
treat them separately to reduce the load on the garbage collector and hence improve
overall performance. Segregating objects this way leaves the heap for objects with
shorter lifetimes and now a typical collection can find more garbage than before.
