14 * The linked-list of pointers to engine types. engine_list_head incorporates-
15 * an implicit structural reference but engine_list_tail does not - the-
16 * latter is a computational optimization and only points to something that-
17 * is already pointed to by its predecessor in the list (or engine_list_head-
18 * itself). In the same way, the use of the "prev" pointer in each ENGINE is-
19 * to save excessive list iteration, it doesn't correspond to an extra-
20 * structural reference. Hence, engine_list_head, and each non-null "next"-
21 * pointer account for the list itself assuming exactly 1 structural-
22 * reference on each list member.-
