#
# Testcases in this file do not work with embedded server. The reason for this
# is that we use the following commands for synchronization:
#
# set @show_explain_probe_select_id=1;
# set debug='d,show_explain_probe_1';
# send select count(*) from t1 where a < 100000;
#
# When ran with mysqltest_embedded, this translates into:
#
# Thread1> DBUG_PUSH("d,show_explain_probe_1");
# Thread1> create another thread for doing "send ... reap"
# Thread2> mysql_parse("select count(*) from t1 where a < 100000");
#
# That is, "select count(*) ..." is ran in a thread for which DBUG_PUSH(...)
# has not been called. As a result, show_explain_probe_1 does not fire, and
# "select count(*) ..." does not wait till its SHOW EXPLAIN command, and the
# test fails.
