-#
-# Then execute the SQL statement, scheduling a crash for part-way through
-# the first sync() of either the database file or the journal file (often
-# the journal file is not required - meaning no crash occurs).
-#
-# After the crash (or absence of a crash), open the database and 
-# verify that:
-#
-#   * The integrity check passes, and
-#   * The contents of table abc is either {1 2 3} or the value specified
-#     to the right of the SQL statement below.
-#
-# The procedure is repeated 10 times for each SQL statement. Five times
-# with the crash scheduled for midway through the first journal sync (if 
-# any), and five times with the crash midway through the database sync.
