 I guess this is a "Ah-ha" bug.

 We cannot safely assign a string variable that is built on the object
 workspace in vcl_hit{} because the object is not locked.

 If two worker threads tries to do it at the same time, they will collide
 like we see here.

 I don't think this will be fixed for 2.0, it will have to be an errata.
