How to write a proper class destructor?

[Bradley Smith]

According to the documentation, a class destructor is "expected to 
release any resources held by the object."[1] However, if resources to 
be released are in objects to be garbage collected, "those references 
are no longer valid."[1]

How is a class supposed to release something for which it no longer has 
a valid reference?
