# This test checks that
# 1. The delayed thread is only running when the server starts on boot
# 2. Connections are possible when the server enters read mode but it is still
#    connecting
#
# To test this:
# 0. The test requires one stopped server.
# 1. Check that the delayed thread is not running when the without start on boot
# 2. Start group replication. Check that the delayed thread is still not there
# 3. Restart server with start on boot. Check that
#    3.1.The read mode is one when connections are allowed
#    3.2.There is a delayed thread running
#    3.3 The join is stuck on debug so the member is still OFFLINE.
# 4. Execute a parallel start request. Check it will fail when we unblock
# 5. Unblock join. Wait for the member to come ONLINE.
# 6. Clean up.
