Review Comment:
As a separate case where timeouts get ignored (besides the hash probe table
construction), a cancel check is needed here for the following query on TDB2:
```sparql
PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#>
SELECT ?x { ?x rdfs:label ?y . ?y rdfs:label ?z }
```
```
time curl http://localhost:3030/ds --data-urlencode 'query=PREFIX rdfs:
<http://www.w3.org/2000/01/rdf-schema#> SELECT ?x { ?x rdfs:label ?y . ?y
rdfs:label ?z }' --data-urlencode 'timeout=1'
```
