  28 # DESCRIPTION:
  29 # Verify ZED handles missed events from a pool when starting.
  30 #
  31 # STRATEGY:
  32 # 1. Create a pool and generate some events.
  33 # 2. Start the ZED and verify it handles missed events.
  34 # 3. Stop the ZED
  35 # 4. Generate additional events.
  36 # 5. Start the ZED and verify it only handles the new missed events.
