# ==== Purpose ====
#
# Sync the slave SQL thread with the IO thread.
#
# ==== Usage ====
#
# [--let $slave_timeout= NUMBER]
# [--let $rpl_debug= 1]
# --source include/sync_slave_sql_with_io.inc
#
# Parameters:
#   $slave_timeout
#     By default, the synchronization timeouts after 300 seconds. If
#     $slave_timeout is set, the synchronization timeouts after
#     $slave_timeout seconds.
#
#   $rpl_debug
#     See include/rpl_init.inc
