------------------------------------------------------------------

Thanks [~jpountz] for sharing this approach. I also feel this approach seems to 
me more generic in terms of handling all types of query. 
So what I currently understand is to have basically have some sort of a wrapper 
class around a {{BulkScorer}} which does the timeout checks inside the 
{{score}} method? Is this method similar to what is being done for all those 
{{*Enum}} classes, where we have a wrapper which takes an instance and does 
timeout checks and then calls the wrapper object's methods?

> While looking into options for LUCENE-10151, I noticed that 
> {{ExitableDirectoryReader}} doesn't actually do any timeout checking once you 
> start iterating postings/impacts. It *does* create a {{ExitableTermsEnum}} 
> wrapper when loading a {{{}TermsEnum{}}}, but that wrapper doesn't do 
> anything to wrap postings or impacts. So timeouts will be enforced when 
> moving to the "next" term, but not when iterating the postings/impacts 
> associated with a term.
> I think we ought to wrap the postings/impacts as well with some form of 
> timeout checking so timeouts can be enforced on long-running queries. I'm not 
> sure why this wasn't done originally (back in 2014), but it was questioned 
> back in 2020 on the original Jira SOLR-5986. Does anyone know of a good 
> reason why we shouldn't enforce timeouts in this way?
> Related, we may also want to wrap things like {{seekExact}} and {{seekCeil}} 
> given that only {{next}} is being wrapped currently.
