>                 Key: SLING-7707
>                 URL:
>             Project: Sling
>          Issue Type: Improvement
>          Components: Extensions
>    Affects Versions: pipes 2.0.2
>            Reporter: Nicolas Peltier
>            Assignee: Nicolas Peltier
>            Priority: Major
>             Fix For: pipes 3.0.0
>          Time Spent: 2h 10m
>  Remaining Estimate: 0h
> pipe that executes its subpipes in sequence or in parallel, with no relation ship between
them, and returns the union of the outputs, like a or / {{+}} operator (as opposed to actual
Container Pipe that chain them together and could be the {{x}} operator)
> Considering subpipe1, subpipe2, ...subpipeN, we could 
> - execute them in sequence (easy case),
> - execute them in parallel (default configuration for performance first, with {{parallel=true}}
& {{maxThreads=5}} (on my laptop heavy thread consumes ~10% CPU except at commit time)
> one important thing to consider is the PipeBinding object should be duplicated and passed
to the subpipe (it's ok to assume container pipe of the executor pipe should not have effects
on its bindings). Use case for this is 
> {{.echo("/content/mysite").children("some:Page").children("some:Page").name("locale").executor("ref1","ref2","ref3","ref4")}}
> should basically call, for each locale, in parallel, "ref1","ref2","ref3" and"ref4",
that all have in their bindings path.locale to work with
