Future.runInFiber

Launch a new fiber that will run the specified callback, set the future when the callback returns

The first form runs F function with all arguments.

The second form does the same, but specified a different context to spawn the fiber in. The first argument can be any object with a spawnFiber function. The most obvious example is a FiberGroup for the fiber to belong to.

The third and fourth forms are for running a supplied delegate instead of an aliased function.
