---------------------------------------------------------------
We do launch Go pipelines in parallel in the test driver:

[~exm] Are you seeing errors or is it because you need different flags for each
pipeline?

> Issue Type: Improvement
> Components: sdk-go
> Reporter: Eduardo Morales
> Assignee: Henning Rohde
> Priority: Minor
>
> It would be nice to be able to launch dataflow pipelines in parallel.
> For example, here is my use case:
> * I consume data produced by my clients/customers.
> * I need to launch a pipeline on an event dispatch.
> * I may receive multiple events, from multiple customers at the same time.
> * Go code could be simpler if synchronization/cooperation wouldn't be needed
> from goroutines handling each customer. In particular, setting options
> through flags is cumbersome.
> * Launching dataflow pipelines serially may not scale if I am able to sign
> up many customers.
