    Description

      We have had reports of data becoming inconsistent between collections and indexes. This appears to be associated with some combination of lookaside eviction and checkpoints. Since that is common, and this has been observed in systems that are not 100% loaded, there may also be another factor involved, such as handles being automatically closed by the sweep thread.

      Enhance testing for consistency in the face of lookaside eviction, checkpoints and sweep.
