I was trying to infer from the previous patches where the frameContexts 
were allocated per frame.. only to find out it is done in later patch 12/19.

the Algorithms::* patches ideally would be arranged in the order of 
their logical calling sequencing ... but it's not the end of the world. :)

So far looks good to me.
