Comment 8 for bug 865859

I used to have a similar destructor in my wrapper class, but I ended up commenting it out, I'm not sure why. I'll re-enable it, but since I somewhat already solved it in my case, it will be difficult for me to know if it affects it. Again, the issue seems to go away magically until you kill a query selecting blobs, then run that query again later. I had a lot of false positive cures until I did that again.
