	# op_recover interface as well as the test code, we create two
	# databases;  one does abort and then commit for each op, the
	# other does prepare, prepare-abort, and prepare-commit for each
	# op.  If all goes well, this allows each command to depend
	# exactly one successful iteration of the previous command.
