# SUMMARY
#
# Waits until the passed statement returns true, or the operation
# times out.
#
# USAGE
#
# let $wait_condition=
# SELECT c = 3 FROM t;
# --source include/wait_condition.inc
#
# OR
#
# let $show_rpl_debug_info= 1; # to force post-failure printout
# let $wait_timeout= 60; # Override default 30 seconds with 60.
# let $wait_condition=
# SELECT c = 3 FROM t;
# --source include/wait_condition.inc
# --echo Executed the test condition $wait_condition_reps times
#
#
# EXAMPLE
# events_bugs.test, events_time_zone.test
#

# calls, and default will be used instead.
