# 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'.

# Test group sematics and thereby failing in such group is bound to 
# the Single-Threaded Slave.
