The only complication I see is that if we want to make it extremely efficient, 
we'll need to double the number of Collector impls for TSDC and TFC (the 
internal instances that are created) ...

I'm not convinced yet.  I think we can likely make it short circuit quite fast 
for the non-paging case, but rather than guess, let's benchmark.  I'm 
extracting my Benchmark collector stuff right now on LUCENE-2343.  I also am 
not sure we need to double the number of collectors.
