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.
