This function configures an "indirect page" in the persistent store's address space. An indirect page is used to hold pivot objects. Each indirect page can hold up to 64 pivot objects, which in this case are the objects referenced by the elements of vector.
The page-num is which page to configure with pivot objects. Page numbers 0-63 are reserved for use by the system[1], and page numbers 64-255 are available for the application.
If more pivot pages are needed, they may be obtained with the alloc-indirect-pages function.
| [1] | Although currently only page 0 is used; it is used to store the standard pivot objects, and it is common practice to use pages 1-9 for application class object pivots. |
