 Description   

After MCOL-5001 there is a possibility to use in-memory exchange b/w EM and PP bypassing local network hop thus reducing time spent in kernel moving data from EM to PP.
The suggested approach is to replace network communication with a queue in DEC class that can be used to send primitive messages(sometimes with data, e.g. for JOINs) from EM to PP.
