I am having a weird issue with testing Coroutines, converted to RxJava2 with `asSingle(CommonPool)`
In a unit-test class, I have 2 different tests. Each one of them uses `test()` method from RxJava2 to assert the value
Problem is, every time I run my tests, on of them fails, but only one of them. If I comment away one of the tests – the other one always passes.
It feels like some threading issue, anybody had similar problems?

Basically, test that is run second always fails in my scenario

Problem was in `CommonPool` that was hardcoded inside the class and not replaced with `Unconfined` in the unit test

Maybe you could provide some self contained example of this issue

```
class ApiCall() {
  fun execute(): Single&lt;Data&gt; {
    async { ... }.asSingle(CommonPool)
  }
}

class ApiCallTest {
   val classToTest = ApiCall()

  @Test
  fun test1() {
   classToTest.execute().test().assertValue(testValue)
  }

  @Test
  fun test2() {
   classToTest.execute().test().assertValue(testValue)
  }
}
```

Along these lines. Do you need actual running example?

Would be great if Kotlin Playground could support 3rd party libraries, like RxKotlin
