      Increase MaxNoOfConcurrentOperations in 'suite/ndb_big/my.cnf' in order to reduce
      failure rates for 'ndb_big.rqg_spj' which repeateadly encounters:
      
      'Got temporary error 233 'Out of operation records in transaction coordinator (increase MaxNoOfConcurrentOperations)'
      
      ... Jonas has previously suggested to increase this in config file.

      Follow up fix to Mikael R's 4G, savemem.patch:
      
      We originally assumed that a specific TC did not communicate with other TCs.
      However, the SPJ block is located in the same block-thread as the TCs.
      
      TC *will* communicate with all SPJ blocks, which should be counted as
      a full TC <-> TC cross communication.
