      Description

      A request to consider a compression option for log files. My first thoughts are that this is doable. I'd probably wrap the existing log subsystem API calls to do the compression before entering the current functions so that the buffer handed to logging is written as-is. We need to consider if it can be reconfigured. If so, we'd need to write it as part of the log file header and turning it on/off would occur on the next file change. I don't want it to be per-record. Or, once set on or off it stays that way forever.
      [~michaelcahill] Let's chat about this when we next talk.
