Possibly. We are currently running extensive tests. So far, the extrq is the only problematic one. I wouldn't be surprised if that happens with the INSERTQI though (I saw that there is similar code in there). I will run some experiments and I will let you know in case.
Would it be okay if in the meatime I commit this change?

Have a nice day,
Andrea
