2001-08-15 Not Zed <NotZed@Ximian.com>
* ibex_block.c (ibex_use): New function to limit use of fd's.
Mark an ibex file in use, re-open if necessary, and close off
another (lru) if necessary.
(ibex_unuse): Mark an ibex as not in use.
(ibex_open): Delay opening of the actual block file till later,
and add the ibex to a global list.
(ibex_save): Use/unuse around operations.
(close_backend): Zero out blocks when closed.
(ibex_close): Remove the ibex from the global list before closing
it down.
(ibex_index_buffer, ibex_find, ibex_unindex, ibex_find_name):
Use/unuse around ops.
