Hi,  
I was trying to learn how to do multi-threading in julia, but everywhere i found just how not to do it  
I need to perform multiple searches in a recursive data structure, and i wanted to try parallelize it. Given it is a recursive data structure, i need to store a refference to a position in the structure for each search  
Nowhere have i found how could i do this, only how should i not do it, could anyone help me?
