* Invoke all remaining finalizers that haven't yet been run.
|
|
* This is needed for strict compliance with the Java standard,
|
|
* which can make the runtime guarantee that all finalizers are run.
|
|
* This is problematic for several reasons:
|
|
* 1) It means that finalizers, and all methods calle by them,
|
|
* must be prepared to deal with objects that have been finalized in
|
|
* spite of the fact that they are still referenced by statically
|
|
* allocated pointer variables.
|
|
* 1) It may mean that we get stuck in an infinite loop running
|
|
* finalizers which create new finalizable objects, though that's
|
|
* probably unlikely.
|
|
* Thus this is not recommended for general use.
