  35 # DESCRIPTION:
  36 #
  37 # Ensure multiple threads performing write appends to the same ZFS
  38 # file succeed.
  39 #
  40 # STRATEGY:
  41 #       1) Verify this is a multi-processor system
  42 #       2) Create multiple threads with each appending to a file
  43 #       3) Verify that the resulting file is the expected size
