      Snaphot 20130317 addresses sub-optimal behavior in the LMDB client
      code that affected tlsmgr and "postmap -i", and it makes the code
      more resilient.

      In particular, the Postfix LMDB client will no longer keep crashing
      on a "database full" error. Instead, Postfix can now recover without
      immediately requiring human intervention. This is important because
      many Postfix databases contain data that is maintained by a Postfix
      daemon process, and the size of the data is not known in advance.

      With this, LMDB no longer requires constant watching for "database
      full" errors. As the system recovers from an error, it logs a warning
      that humans can take care of the next day.
