Sure, I understand, what I fail to understand is how putting
wait_for_last_checkpoint_event() into the user's connection thread helps
avoid this. The user thread waits for the checkpoint event of the new binlog
file, however the SST thread already did its wait for its own
reload_acl_and_cache(), it will not wait again... ?
