  SVN rev 220922 on 2011-04-21 13:31:43Z by pjd
  
  Instead of allocating memory for all the keys at device attach,
  create reasonably large cache for the keys that is filled when
  needed. The previous version was problematic for very large providers
  (hundreds of terabytes or serval petabytes). Every terabyte of data
  needs around 256kB for keys. Make the default cache limit big enough
  to fit all the keys needed for 4TB providers, which will eat at most
  1MB of memory.
