Class
ZODB.utils.WeakSet

A set of objects that doesn't keep its elements alive.

The objects in the set must be weakly referencable. The objects need not be hashable, and need not support comparison. Two objects are considered to be the same iff their id()s are equal.

When the only references to an object are weak references (including those from WeakSets), the object can be garbage-collected, and will vanish from any WeakSets it may be a member of at that time.
