SOLR-5986 looks like a great enhancement for enforcing timeouts. I'm curious about how to handle *manual* cancellation.
We're working on backup requests -- e.g. wait till 90% of shards have responded then send out a backup request for the lagging (e.g. GC, cache miss, overloaded, etc.) shards after a configurable delay -- and would like to be able to cancel the slower to respond shard. From what I can see in SOLR-5986, I'm not sure that Solr will check the interrupt status of a thread if it is manually interrupted. Am I reading that right? If so, would it make sense to add a check for the interrupt status in SolrQueryTimeoutImpl#shouldExit()[1]?
