Yep, looks like I was falling victim to insert_missing, both in my original
issue and in the testing code I posted earlier. I can't believe I didn't see
it before (doh!). I still don't completely understand why add_smooth would
cause a track change (and thus trigger map_metadata to call if
using insert_missing), but regardless, it works now, and that's all that
matters :).
Thank you so much to everyone at and involved in savonet. Liquidsoap is the
best thing since sliced bread, and it rescued me from weeks of pain and
suffering with sc_trans and ices.

All of the data generated in your IT infrastructure is seriously valuable.
Why? It contains a definitive record of application performance, security
threats, fraudulent activity, and more. Splunk takes this data and makes
sense of it. IT sense. And common sense.
