I don't understand how this is suppose to work. We don't have weak references in
Dart, so these entries will never be removed. Seems like we need a bigger
re-write than these two methods.

Done.

   private void markRemovedContext(AnalysisContext context) {
     removedContexts.put(context, WEAK_SET_VALUE);
   }
