One producer two consumer loops, dequeue same element in both consumers

Question

Hi!
What is the best way for the following:
I enqueu data in my producer loop. I need this data dequeue-d in both of my consumer loops, but I want to dequeu the same element in both loops.
Of course if I put dequeues in both loop, then the second consumer loop will loose the odd elements and the first consumer loop will loose the even elements.
thanks!

Makes very little sence- that is, the problem is stated in such a way as to preclude an informative response

either create two queues or use notifiers...

Usually, Gerd gives good advice but on this one I'm going to pick on him just a bit- I bet he rushed in just a tad without thinking about the premise of the OP's question - and Gerd I don't mean to sound mean, my appologies
The question pre-supposes that to use a queue element twice in parallel it must be read twice.  This is false and led to less than optimal advice.  What about a template like shown in this snippet? 
We can certainly dequeue once and spawn as many independant actions as we need within a single consumer loop!  Much more scalable than creating a queue for each action.
