Shouldn t suspendApp be shutting things down gracefully

gt Shouldn t suspendApp be shutting things down gracefully There is no such thing as magic sweat smile You still need to properly use `Resource` and compose things Not that `ctrl+c` is not properly handled by Gradle and it forcefully terminates the application `SIGKILL` Hard to say what is going on without any code
