> In Threader.gatherSubjects, it appears to be possible for tail.next = c.child; to be
null [line 356]:
> 	349	 if (old.threadable == null && c.threadable == null) {
> 	350		// both dummies - merge them
> 	351		ThreadContainer tail;
> 	352		for (tail = old.child;
> 	353		tail != null && tail.next != null;
> 	354		tail = tail.next);
> 	355	
> 	356		tail.next = c.child;
> It also seems kind of pointless, given that the subsequent line immediately resets tail
to c.child. Perhaps the ; is not intended there?
