Distributed garbage collection

Distributed Garbage Collection (DGC) is a particular case of Garbage collection (computer science) where references to an object can be held by a remote client.

DGC algorythms typically rely on a time lease set on the Object; it's the Remote Client's stub object task to periodically renew the lease on the remote object. If the lease is expired, the GC engine can safely assume that the Remote Client is no longer interested in the Object, hence proceed to Garbage Collection.
