Broken Scala Native tests on v1.0.0-M9 about munit

[valencik]

One tiny step further, we can drop the Thread.sleep() and still get the failure on native.
Note that this now also runs on Scala JS and passes there.

//> using dep org.scalameta::munit::1.0.0-M9
//> using nativeVersion 0.4.15

import scala.concurrent.duration.*
import scala.concurrent.*

class MySuite extends munit.FunSuite:
  override implicit def munitExecutionContext = ExecutionContext.global

  test("boo"):
    val p = Promise[Unit]()
    ExecutionContext.global.execute { () => p.success(()) }
    p.future

scala-cli test --native iss695.scala

MySuite:
  + boo 0.00s
Test runner interrupted by fatal signal 9
Error: scala.scalanative.testinterface.common.RPCCore$ClosedException: scala.scalanative.testinterface.NativeRunnerRPC$RunTerminatedException

scala-cli test --js iss695.scala

MySuite:
  + boo 0.00s

from munit.

I'm operating under the assumption that this is a CE bug, but I'm not sure yet.

I was able to reproduce without CE.

  test("boo"):
    val p = Promise[Unit]()

      Thread.sleep(1000)
      p.success(())
    }
