Tracing Coroutines on a JVM

This talk by Tyson Henning addresses the challenges of propagating tracing information, such as OpenTelemetry or Dapper, through coroutines on the JVM. It delves into the problem's discovery and presents a solution using `CopyableThreadContextElement` to safely propagate traces in hybrid Java Executor/Kotlin Coroutine environments by leveraging `ThreadLocal` storage. The discussion covers how this mechanism ensures accurate traces and simplifies span syntax when integrating with existing Java and JVM infrastructure.
