   If you use Chaitin's allocator, you don't need a separate local   
   allocator.  It's one of the attractive features.   
      
   Many other global allocators are also able to solve local allocation.   
   After all, local allocation is an easier problem.  I expect the reason   
   some people use a separate local allocator is that they have a bright   
   idea about how to do a better job on the simpler problem, so they try   
   it out.
