Works for me (on the test data from before).
tdbloader --loc DB ~/Desktop/1k_news.nq.gz
tdbquery --loc=DB --file=Q.rq
=> result model.
Iterators count as read operations - you can't update a model and
continue to iterate over results (which is what CONSTRUCT is doing).
sync'ing a dataset is a write operation.

PS The file extension for SPARQL queries is ".rq". The extension for
SPARQL Update is ".ru" (where "is" is defined to be "when the W3C
registers the MIME type").
