The core idea is derived from a concept I call: "on-demand-recovery-design". Assuming that inadvertent deleting of files or directories does happen, we can help the absent minded customer by keeping around the just-freed resources (i.e file pages and inodes). To that end a new allocation scheme should be used: FirstRemovedFirstAllocated (FIFO order).
