Fibra grows Tubes.

Tubes are like pipes, but... different. Anyhow, Fibra 0.0.9 includes some new Tube classes for communicating amongst tasks.

import fibra

def a(tube):
    print 'Pushing "a" into tube.'
    tube.push('a')
    yield  None

def b(tube):
    while True:
        x = yield tube.pop()
        print 'Received "%s" from tube.'%x

t = fibra.Tube()
schedule = fibra.schedule()
schedule.install(a(t))
schedule.install(b(t))
schedule.run()
