Hi deadalnix,

currently skimming through all the commits on top of Core chronologically, to familiarize myself with everything. This fragment you changed caught my eyes:

else if (RecursiveDynamicUsage(*ptx) < 100000) {
           AddToCompactExtraTransactions(ptx);
       }

in net-processing.cpp. This seems to be the opposite of short-circuit evaluating fWitness to false, which you apparently did everywhere else. Don't have the high level view yet whether it still fits, however ...
