spawn X different workers & wait for results from all of them

[Robert M. Münch via Digitalmars-d-learn]

Hi, I'm not sure how to best implement the following:

1. I have 4 different tasks to do.
2. All can run in parallel
3. Every task will return some result that I need

Now how to best do it? When using receive() it fires on the first hit 
and the function continues. It's like a receive(OR), one hit and it's 
done. So, I would need something like a receive(ALL) that continues 
only of all results (messages) have been received.

Is something like this available or do I have to build it myself?
