13+

14+
* 1. By using the debug mode, via the stacktrace recovery mechanism; see
15+
* [stacktrace recovery](https://github.com/Kotlin/kotlinx.coroutines/blob/master/docs/topics/debugging.md#stacktrace-recovery)
16+
* documentation. The usual way to enable the debug mode is with the [kotlinx.coroutines.DEBUG_PROPERTY_NAME] system
17+
* property.
18+
* 2. By looking at the output of DebugProbes; see the
19+
* [kotlinx-coroutines-debug](https://github.com/Kotlin/kotlinx.coroutines/tree/master/kotlinx-coroutines-debug) module.
