 One of the backtraces I copied does answer this:
 
 	src/lib/libc/compat/sys/compat___sigaction14_sigtramp.c:68
 
          /*
           * We select the non-SA_SIGINFO trampoline if SA_SIGINFO is not   
           * set in the sigaction.
           */
 
 
 and tcsh does:
 
     struct sigaction act;
  
     act.sa_handler = fn;
     sigemptyset(&act.sa_mask);
     act.sa_flags = 0;
     if (sigaction(sig, &act, NULL) == 0) {
