      YCSB load phase, running with no journal, oplog size 2GB, cache_size 2GB.
      Inserting 30M documents fieldcount=1 (so 151 bytes each).

      After period of time the inserts stall, seemingly forever waiting for eviction threads.

      Have also reproduced this with journal - needed a smaller cache (used 1G).
