Hi @fisk, thanks for the amazing cleanup! We've had a bunch of issues with the code sweeper and AsyncGetCallTrace with trying to unwind from dead code blobs (or what looked like it at least). Have you run some stress tests for AsyncGetCallTrace and this change? It may be something we can look into to make sure it doesn't increase the chances of crashes, or even reduces the chances of crashes. CC @jbachorik @parttimenerd
