The thd->handler_tables list is kept as-is to avoid deadlocks if
open_table(), called by open_tables(), needs to back-off because
of a pending name-lock on the table being opened.
of a pending exclusive metadata lock or flush for the table being
opened.
See open_table() back-off comments for more details.
