SPARQL. LOAD <…> INTO <…>. File size limit

Looks like there is a file size limit on `LOAD <…> INTO <…>` command. I use it to import datasets from filesystem on-demand. It works fine for small datasets, but fails for larger ones.

I got this error:

```
Virtuoso 39000 Error FA008: File '/path/to/file.nt' too long, cannot return string content 62172163 chars long
```

In this case, file in question is [DBPedia "instance types" dictionary](http://downloads.dbpedia.org/3.8/en/instance_types_en.nt)
