--- Comment #8 from Ben Nham <nham at apple.com> ---
Going to take a stab at this. From looking at SQLiteIDBBackingStore.cpp, it looks like there are several places where we only step a cached prepared statement until it hits SQLITE_ROW and then immediately return (like uncheckedGetKeyGeneratorValue). The problem is that cursor will hold open a read transaction to that version of the table, preventing checkpointing from ever moving past the pages associated with that version of the table.

We need to ensure all cached prepared statements are iterated until they hit SQLITE_DONE or we sqlite3_reset them; both will cause the associated transaction to be dropped.
