#
# Stress the storage engine with rapid CREATE/DROP TABLE/INDEX
# and following SELECT/INSERT/SHOW etc.
# Subtest 4 variants (4A - 4D)
#
# The variables
# $loop_size -- number of rounds till we look at the clock again
# $runtime -- rough intended runtime per subtest variant
# $engine_type -- storage engine to be used in CREATE TABLE
# must be set within the routine sourcing this script.
#
# Other stuff which must already exist:
# - connection con2
# - stmt_start and stmt_break prepared by the default connection
