  Modified files:
    lib/libc/stdlib      malloc.c 
  Implement chunk allocation/deallocation hysteresis by caching one spare
  chunk per arena, rather than immediately deallocating all unused chunks.
  This fixes a potential performance issue when allocating/deallocating
  an object of size (4kB..1MB] in a loop.
