An exercise in cooperative asynchronous programming.

Building:

pub get
dartanalyzer lib example

Running:

dart example/example1.dart

or perhaps save some text lines to 'hello.txt' and then

dart example/example1.dart < hello.txt

What's here

See scheduler.dart it defines a class Scheduler that executes several Process instances in lock-step round robin fashion. The processes are cooperative and must periodically yield back to the scheduler. Additionally if a process state indicates that it is blocked, we kick it off the round-robin queue and into a new Future that will wait for the process to signal that it is ready to run again at which point it goes back on the queue.
