Breaking changes

• Kotlin's fiber function has been moved to the co.paralleluniverse.kotlin package, has several convenient overloads and by default will also start the fiber.

New features

• co.paralleluniverse.kotlin also includes a convenient select syntax to perform channel selection:

val ch1 = Channels.newChannel<Int>(1)
val ch2 = Channels.newChannel<Int>(1)

assertTrue (
    fiber {
        select(Receive(ch1), Send(ch2, 2)) {
            it
        }
    }.get() is Send
)

ch1.send(1)

assertTrue (
    fiber {
        select(Receive(ch1), Send(ch2, 2)) {
            when (it) {
                is Receive -> it.msg
                is Send -> 0
                else -> -1
            }
        }
    }.get() == 1
)

• The new FiberForkJoinScheduler.onIdle() hook notifies when the fiber scheduler becomes idle.
