Currently, rpl_semi_sync is failing in PB due to the warning message: "Slave SQL: slave SQL thread is being stopped in the middle of " "applying of a group having updated a non-transaction table; " "waiting for the group completion ..." The problem started happening after the fix for BUG#11762407 what was automatically suppressing some warning messages. To fix the current issue, we suppress the aforementioned warning message and exploit the opportunity to make the sentence clearer.

# Proving that stopping in the middle of applying a group of events
|
|
# does not have immediate effect if a non-transaction table has been changed.
|
|
# The slave sql thread has to try to finish applying first.
|
|
# The tests rely on simulation of the killed status.
|
|
# The matter of testing correlates to some of `rpl_start_stop_slave' that does
|
|
# not require `have_debug'.
