There's probably a bug somewhere in how we handle retries when storing performance data, probably due to the "bulk insertion" logic in the artifacts model. This will be a lot easier to fix once we have bug 1306674 and can trivially serialize this operation. Let's just wait for that.

Sounds good to me :-)

I believe this error is no longer possible now that bug 1318027 has landed.
