A modern programming language that makes developers happier.

kotlinlang

if all my `Dispatchers.Default` threads (`Runtime.getRuntime().availableProcessors()`) are blocked under `runBlocking`, a `GlobalScope.future(<http://Dispatcher.IO|Dispatcher.IO>)` also fails to launch; why is this the case?

If all CPU cores are tied up, there’s literally no compute resources left to spawn IO threads. <http://Dispatchers.IO|Dispatchers.IO> threads are still running on the same physical hardware that Dispatchers.Default are, even if the thread pools are different

<@UD17D4K8W>, the cores are probably idle. Only the thread are blocked. <@UMGPA5ZAS> runBlocking is not allowed inside a coroutine.

`This function should not be used from a coroutine. It is designed to bridge regular blocking code to libraries that are written in suspending style, to be used in main functions and in tests.`
