# if heartbeat is disabled then reconnecting to the idle master
# should happen with `slave_net_timeout' period.
# Since it's the real time that is measured, `slave_net_timeout'
# merely guarantees that reconnecting can *not* happen earlier of a value specified.
# That is there can't an exact estimate for how many time it will happen.
#
# The following lines verify that having idle master
# for more than 2 * slave_net_timeout seconds and
# slave.net_read_timeout < slave_net_timeout
# won't cause reconnecting by the slave within at least
# slave_net_timeout interval.
