To recreate the -# problem do this: -# -# (1) Create a table with an index. Insert some data into that table. -# (2) Start a query on the table but do not complete the query. -# (3) Try to delete a single entry from the table. -# -# Step 3 will fail because there is still a read cursor on the table. -# But the database is corrupted by the DELETE. It turns out that the -# index entry was deleted first, before the table entry. And the index -# delete worked.
