setting chunksize to 20 (1MB) and using memcache will cause the allocator
to use vmalloc() instead of kmalloc().  vm space is a bit limited on
some systems.  using the memcache i wouldnt consider a chunksize over 15.
since your cache is generally smaller with memcache bigger chunksizes
tends to force the number of files you can hold to a smaller number.
