The Pipeline Basics tutorial has now been incorporated into the project
page. Thanks to some help and cleanup from Rahul Akolkar the
documentation submitted was installed quickly. See

Hi,
I am playing with pipeline, and I have some questions regarding to usage.
What is the suggested method of avoiding "traffic-jam" in the pipe? I mean,
when a stage produces results fast, followed by a long-running stage. I will run out of
stack space in large amount of input data.
Currently, my solution uses the context raise/registerListener methods. The slow stage
notifies it's "feeder" stage, that new data can be processed. Is there any
better ideas for this problem?
My other issue is about branches. Is there a way to attach separated branches
together? For example, a stage needs input from two different branches. Is
there any solution to apply a synchronized data flow? (Lets say I have two
branches, one produces A-s, and the other produces B-s. I want a stage, that is
being fed by those two branches, and produces a sequence of ABABAB...) Is there
an implementation for such behaviour?
Finally, I am interested about the various StageDrivers. I'd like some more
detailed informations
then the API. Especially usage advices, samples, to help choose the best
stagedriver for the certain stages.
Thanks in advance for your time,
Istvan Cseh
