      Description

      This is a spinoff from SERVER-19954. Repro scripts are there.

      Once there are more than 10K tables, I now see all the time being spent opening and closing sessions and cursors, because the caching layer bounds how many we keep open since 3.0.6. I can code around that, but then I'm not testing how the system actually behaves.
