Great, thank you!

Good point, I'll add one.

I do have:

  inc_metric("error_count","lzma",to_string(rc));

in lzma_exception and:

  inc_metric ("http_responses_total","result",metric);

in create_buildid_r_response, which gets called with
metric = "seekable archive".  But I'll add another metric for attempts,
and name the existing one "seekable xz archive" to be more explicit.
