  Log:
  Minor improvements to arc4random():
  
  - Decrease reseeding interval from every 64 to every 16384 runs
    to reduce entropy usage.
  - Add time based reseeding.  (Every 5 minutes.)
  - Throw away the first 256 words of output as suggested in
    "Weaknesses in the Key Scheduling Algorithm of RC4."
