+#***********************************************************************
+# This file implements regression tests for SQLite library.
+#
+# This file implements tests to verify that ticket [b72787b1a7] has been
+# fixed.  From the ticket:
+#
+#     The sqlite3ExpirePreparedStatements routine marks all statements
+#     as expired. This includes statements that are not expired.
+#
+#     Steps to reproduce:
+#
+#        * Prepare a statement (A)
+#        * Alter the schema to invalidate cookie in A
+#        * Prepare a statement (B)
+#        * Run B and have A run as part of B
+#        * A will find a bad cookie and cause *all* statements
+#          to be expired including the currently running B by calling
+#          sqlite3ExpirePreparedStatements
+#        * When control returns to B it will then abort 
+#
+#     The bug is that sqlite3ExpirePreparedStatements expires all statements.
+#     Note that B was prepared after the schema change and hence is perfectly
+#     valid and then is marked as expired while running.
