-**     any function calls nor subqueries nor references to b-trees other than
-**     the cursor being hinted.
-**
-**     The design of the _RANGE hint is aid b-tree implementations that try
-**     to prefetch content from remote machines - to provide those
-**     implementations with limits on what needs to be prefetched and thereby
-**     reduce network bandwidth.
-**

-** because locks cannot be obtained, but no other error occurs, this
-** function returns SQLITE_BUSY.
-**
-** If any other error occurs while flushing dirty pages to disk (for
