> Usually when you pull an NRT reader, you want all deletes to be applied.
> But in some expert cases you may not need it (eg you just want to validate 
> that the doc was indexed).  Since it's costly to apply deletes, and trivial 
> to add this boolean (we already have a boolean internally), I think we should 
> add it.
> The deletes are still buffered, and you can always later pull another reader 
> (for "real" searching) with deletes applied.
