+    
+    
+        If this is not done, GDB will get confused in the following.  For example,
+        "info threads" will stop early with "bogus thread id 6 Can't fetch
+        registers from thread bogus thread id 6: No such thread".
+    
+        Calling delete_exited_threads instead of prune_threads does not work.
+    
+        It's not clear if this really should be called here, or if we fail to
+        properly track/report our own threads.  For example, we're not calling
+        delete_thread anywhere.
+    
+        Alternatively, should/could we provide a update_thread_list function, and
+        do the pruning there?
+    
+    TODO.
