      Description

      Hi!

      We found that sometimes we can lose records after application crash even when we run with log=(enabled),transaction_sync=(enabled,method=none)

      Docs says that in that case "updates durable after application failure, but not after system failure"

      Please see simple test attached:

      $ ./recovery-test
      		 
      no record with key 261966
      		 
      1 record(s) absent from 261967

      Thanks!
