what does happen with a regular kotlin coroutine ?
The following code works well with regular thread pools. The problem is related to the thread pool managed by Vert.x/vertx-lang-kotlin.
@Test
fun `it works well with standard dispatchers`(): Unit = runBlocking {
val dispatcher = Executors.newFixedThreadPool(4).asCoroutineDispatcher()
val scope = CoroutineScope(dispatcher + SupervisorJob())
scope.async {
(0 until 1000).forEach {
yield()
yield()
}
}.await()
}from vertx-lang-kotlin.

Any updates on this? I face this problem regularly when trying to use yield() in Verticles even with a single yield() call in some cases.
A stack trace from a real-world app when the latest coroutines and vert.x libraries are used:
