Nested runBlocking and init block

[fvasco]

I found a trouble in the follow code:

import kotlinx.coroutines.launch
import kotlinx.coroutines.runBlocking

object A {
    var ok = false

    init {
        println(1)
        runBlocking { }
        println(2)
        ok = true
        println(3)
    }

}

fun main() {
    runBlocking {
        launch { println(A.ok) }
        launch { println(A.ok) }
    }
}

I expect:

1
2
3
true
true

but it is:

1
false
2
3
true

openjdk version "11.0.6" 2020-01-14
kotlin 1.3.70
coroutine 1.3.4

This is the same problem as described #1697 (see my explanation here)

It is basically a tradeoff between "nested runblocking just hangs the thread and you have a deadlock" and "nested runblocking sometimes confuses people"
