Nope, that's not it. It's the patch that fixes the re-parenting of a process
that's about to exit. The bug was in the section of forget_original_parent()
that could erronously select a thread from the threadgroup as a suitable reaper,
while that thread had in fact allready done do_exit() itself:

-       /* Next in our thread group */
-       reaper = next_thread(father);
+       /* Next in our thread group, if they're not already exiting */
+       reaper = father;
+       do {
+               reaper = next_thread(reaper);
+               if (!(reaper->flags & PF_EXITING))
+                       break;
+       } while (reaper != father);
+
