** Test overview:
**
**   1. Insert (Datatest4.nRec) records into a database.
**
**   2. Repeat (Datatest4.nRepeat) times:
**
**      2a. Delete 2/3 of the records in the database.
**
**      2b. Run lsm_work(nMerge=1).
**
**      2c. Insert as many records as were deleted in 2a.
**
**      2d. Check database content is as expected.
**
**      2e. If (Datatest4.bReopen) is true, close and reopen the database.
