1. Slower performance shows that parallel execution of query across slices
is a good thing. 
2. This also tells us that we should not dismantle parallel execution
unconditionally. What I proposed is  
      a) execute queries in parallel when openjpa.Multithreaded=false (which
is default) 
and b) execute queries sequentially when openjpa.Multithreaded=true. 

  ....Till we find a smarter/better way.  

This can be done without perturbing things too much within
