I am a registry for objects needing finalization. When an object is added the object as well as its executor is stored. When the object is garbage collected, the executor can take the appropriate action for any resources associated with the object.

	size Answer how many elements the receiver contains.
	species Answer the preferred class for reconstructing the receiver. For example, collections create new collections whenever enumeration messages such as collect: or select: are invoked. The new kind of collection is determined by the species of the original collection. Species and class are not always the same. For example, the species of Interval is Array.

	adding	top
	add: Add anObject to the receiver. Store the object as well as the associated executor.

	enumerating	top
	do: Evaluate aBlock with each of the receiver's elements as the argument.

	finalization	top
	finalizeValues Some of our elements may have gone away. Look for those and activate the associated executors.

	initialize	top

	printing	top
	printElementsOn:

	private	top
	protected: Execute aBlock protected by the accessLock

	removing	top
	remove:ifAbsent: Remove oldObject as one of the receiver's elements.

	instance creation	top
	new Answer a new instance of the receiver (which is a class) with no indexable variables. Fail if the class is indexable.
	new: Answer an instance of this class with the number of indexable variables specified by the argument, sizeRequested.
