  1. Improve performance of statistics queries 

    Without this, the many sub-queries in stats calculations that JOIN the
question_references table dont hit any of the indexes on that table. For
sites with large question_references tables - this can be horrible for
performance as it ends up doing a seqscan on that table.

By adding the usingcontextid field, we instead get indexscan's.
