+# To roll back a hot-journal file, the application needs read and write

+# the case.
+# 
+#   tkt3457-1.2: Application has neither read, nor write permission on
+#                the hot-journal file. Result: SQLITE_CANTOPEN.
+#                
+#   tkt3457-1.3: Application has write but not read permission on
+#                the hot-journal file. Result: SQLITE_CANTOPEN.

+#   tkt3457-1.4: Application has read but not write permission on
+#                the hot-journal file. Result: SQLITE_CANTOPEN.

+#   tkt3457-1.5: Application has read/write permission on the hot-journal 
+#                file. Result: SQLITE_OK.
