+    CA2213 - IDisposable types should Dispose any IDisposable fields. This rule finds over 600
+                examples! These are all in subtle multithreaded or async code. Some of them appear
+                not to be real problems. For example, there are places where schedulers retain
+                references to IDisposable work items, but that IDisposable interfaces is only there
+                to enable application code to cancel scheduled work, so it's not Rx's place to call
+                Dispose. And there are more subtle cases where disposal is deferred to give threads
+                a chance to shut down. Each of these likely needs individual review:
