      SERVER-83492, HELP-52304. The symptom is that queries are timing out with a maxTimeMS at 1s. The cause was that $limit and $skip values were hardcoded into the SBE plancache.

      Maybe we can simulate this by repeatedly clearing the plancache.

      SERVER-83712, SERVER-82548, HELP-51946 The symptom is that queries spend a long time planning. This was due to getting a separate plancache entry for each $in array size.

      Result - run this scenario in the testing harness against the placeholder algorithm
