BETTER PLACEMENT OF DYING OBJECTS IN A GENERATION MANAGED BY THE TRAIN ALGORITHM

In a garbage collector that employs the train algorithm, some objects in the collection set are evacuated from the collection set, even though they are referred to only by weak references, in order to keep the data that they contain available for post-mortem processing. The destinations to which at least some such objects are evacuated are chosen independently of where the weak references to them are located.
