This is exactly what worries me. Should that planning be done "outside" of 
boost framework? For example, if I am using features provided by ::interconnect 
library - how am I suppose to take multi-core technology into account if, say, 
"shared memory" already locks me into a solution where I don't have much 
control on anything multi-core and where "multi-core" is not even present as a 
concept?
