kotlinlang

is it thread safe to iterate over job’s children `job.children.toList()`? By looking into source seems should be fine, but want to confirm

&gt; All functions on this interface and on all interfaces derived from it are thread-safe and can be safely invoked from concurrent coroutines without external synchronization.

Pro tip: You can iterate a children sequence as is _live_, without doing `toList()`. New children launched while you iterate are added to the end, so `job.children.forEach { it.await() }` actually waits for all children, even when some children launch new children.
