Comment (by fgsch):

 From a quick look at the code I think the right way is to setup a sighup_f
 function that returns 1, so the loop in VUT_Main() is broken:

 {{{
                 if (VUT.sighup && VUT.sighup_f) {
                         /* sighup callback */
                         VUT.sighup = 0;
                         i = (VUT.sighup_f)();
                         if (i)
                                 break;
                 }
 }}}

 btw, rotateout should only be used if the programs are running as daemon
 (VUT.d_opt equals 1).
 This looks like a bug to me in the current code.
