Coroutines

Some experiments

Coroutines.kt

[L8:T0ms:mainThread]	 Start execution
[L17:T147ms:mainThread]	 suspend main function delay 2 seconds coroutine
[L12:T150ms:DefaultDispatcher-worker-1Thread]	 Global Scope launch coroutine delay 1 second
[L14:T1163ms:DefaultDispatcher-worker-1Thread]	 Hello
[L21:T2165ms:kotlinx.coroutines.DefaultExecutorThread]	 Stop execution

CoroutineScope.kt

[L22:T1ms:mainThread]	 Task from coroutineScope - context: [ScopeCoroutine{Active}@51521cc1, BlockingEventLoop@1b4fb997]
[L12:T106ms:mainThread]	 Launched task from runBlocking - context: [StandaloneCoroutine{Active}@593634ad, BlockingEventLoop@1b4fb997]
[L18:T806ms:mainThread]	 Launch task from coroutineScope - context: [StandaloneCoroutine{Active}@20fa23c1, BlockingEventLoop@1b4fb997]
[L25:T807ms:mainThread]	 runBlocking after coroutineScope ended - context: [BlockingCoroutine{Active}@3581c5f3, BlockingEventLoop@1b4fb997]
