> I looked at ExitableDirectoryReader and to me checking the timeout on every
> term is a pretty heavy operation. I wonder if we can relax that a bit and
> begin with checking when we pull Terms and maybe only every Nth term by
> default? I wonder if we even can make it a function of the number of therms
> ie log(numTerms) I think it's pretty trappy to have something that won't
> perform well or has the risk to not scale well in lucene core?
