Currently we default to 0/5, which means we collect log messages on messages sent and received and dump them on crash. The intent is that on a crash we'll have some additional useful context.

And Radek's testing is suggesting we get quite a bit of additional performance on the OSD side by turning this down. Has anybody else found this information to be useful in real world debugging situations?
