Public bug reported:

I wrote the following query:
import module namespace file ="http://expath.org/ns/file";;
 
for $line at $i in file:read-text-lines("doc.xml")
return
  if($i lt 1104869) then () else concat($line, "
")

Where doc.xml is a large document.
The result of the query is not streaming and its memory footprint is huge.
