  Print more info about a trx in SHOW INNODB status; try to find the bug reported by Plaxo
buf0buf.c:
  Check that page log sequence numbers are not in the future
log0recv.c, log0log.c:
  Fixed a bug: if you used big BLOBs, and your log files were relatively small, InnoDB could in a big BLOB operation temporarily write over the log produced AFTER the latest checkpoint. If InnoDB would crash at that moment, then the crash recovery would fail, because InnoDB would not be able to scan the log even up to the latest checkpoint. Starting from this version, InnoDB tries to ensure the latest checkpoint is young enough. If that is not possible, InnoDB prints a warning to the .err log
