I am having a hard time upgrading from 3.1. Given this production class

class App {
	companion object {
		val threadLocal: ThreadLocal<String> = ThreadLocal()
	}

	val greeting: String
		get() {
			return threadLocal.get()
		}
}

this test is successful in `3.1`m but fails in 3.2 and 3.3

import io.kotlintest.Description
import io.kotlintest.Spec
import io.kotlintest.shouldBe
import io.kotlintest.specs.StringSpec

class AppIntegrationTest : StringSpec() {
	override fun beforeSpec(description: Description, spec: Spec) {
		App.threadLocal.set("test")
	}

	init {
		"greetings" {
			App().greeting shouldBe "test"
		}
	}
}

from what I was able to grasp, it seems 3.1 was running tests in kotlintest thread, while 3.2+ is using a thread pool. can I configure thread pool for kotlintest?
