@Volatile
In order to force changes in a variable to be immediately visible to other threads, we can use the annotation @Volatile, a in the following example:
@Volatilevar shutdownRequested = false
This will guarantee visibility of changes for other threads as soon as the value is changed. This means that if thread X modifies the value of shutdownRequested, thread Y will be able to see the change immediately.
Notice that @Volatile is only available in Kotlin/JVM. For other platforms, it's not available since it relies on the JVM to guarantee volatility.
