    nmalloc - Try bigcache in posix_memalign() for big PAGE_SIZE aligned allocs.
    
    * This improves performance (by reducing the amount of mmap() calls required
      and avoiding some amount of page faults) for applications which frequently
      call posix_memalign() with a 4096 byte alignment for allocations bigger
      than 8KB. Allocations of 8KB and smaller are efficiently handled by the
      SLAB allocator already.
