Hello,

I have a little question about how pre-emption works with the 
FiberScheduler. Let's say I create 100.000 fibers that all run 
long-runners (such as calculating fibonacci(100)). Now I start 
another fiber that just prints "hello world" to the console. So 
it's a short runner. When can I expect "hello world" to appear on 
the console?

a. Will take a long time in case fibonacci(100) never does any 
yield.
b. The FiberScheduler will do a yield periodically. So "hello 
world" will be displayed in not so long time
c. I need to do a yield from within the fibonacci function here 
and then for "hello world" to be displayed in not so long time

Just for my understanding ...
Thanks, Bienlein
