      Description

      Experimentation with TBB memory manager, or TCMalloc or SuperMalloc show very significant speed increases with some queries which are highly threaded.
      An example is Thor using channelsPerSlave=X and a tight looping child query.

      In case like those, a 10 fold speed increase has been observed simply by slotting in a replacement allocator.
