/* Module start-up and shut-down hooks.  Not installed.
 *
 * das_init() and das_finish() in util.c are the only callers, so the hooks
 * are declared next to them rather than in each module's public header.  The
 * defining .c files include this too, so the compiler checks each definition
 * against its declaration.
 *
 * None of these are thread safe, they run once from das_init() before any
 * worker threads exist.
