# $engine_type storage engine to be tested
#
# Last update:
# 2009-02-13 HH "Release_lock("hello")" is now also successful when delivering NULL,
# replaced two sleeps by wait_condition. The last two "sleep 1" have not been
# replaced as all tried wait conditions leaded to nondeterministic results, especially
# to succeeding concurrent updates. To replace the sleeps there should be some time
# planned (or internal knowledge of the server may help).
