# DESCRIPTION:
# Verify ZED handles missed events from a pool when starting.
#
# STRATEGY:
# 1. Clear the events and create a pool to generate some events.
# 2. Start the ZED and verify it handles missed events.
# 3. Stop the ZED
# 4. Generate additional events.
# 5. Start the ZED and verify it only handles the new missed events.
