[concurrency-interest] Object finalization

I could not find any resources that I felt were clear and trustworthy
enough, so...

I would like to have confirmed (or busted) my assumption that the following
code is buggy, because the garbage collector might set the `a` field to
null, before this `finalize` method can read it, thus preventing the method
from attempting to cleanly dispose of the `Resource` in the `b` field —
this all under the assertion that `safelyDispose` itself never throws:

public class SomeService {
  private final Resource a, b;

  public SomeService(Resource a, Resource b) {
    assert a != null && b != null;
    this.a = a;
    this.b = b;
  protected void finalize() throws Throwable {
