Evidence of multiple REST requests using same trace file

[bobbingwide]

While testing a minor change to oik-magnetic-poetry's server side rendering I noticed that it was very slow.
The trace file for the request appeared to be recording duplicate events.
This was confirmed by looking at the daily trace summary and the trace file itself.

I noticed that it was very slow.

Actually it was diabolical, even when the same file wasn't being used by two requests.
