 Memory Allocator perfomance benchmark
------------------------------------------------------------------------

local_n = n threads allocating and deallocating random blocks of max 
          size. Deallocations always happening in the same thread that
          the corresponding allocation.
share_n = n threads allocating and deallocating random blocks of max
          size from a shared list. Deallocation may happen in different
          thread that the allocation one
