Actually I still can't quite get signal handling in MinTTY to work 
right. SIGINT is fine, but SIGTERM, SIGHUP, and SIGKILL don't seem to 
get to sigwait(), instead still invoking the default handler, i.e. 
terminating MinTTY without SIGHUP being sent to the command inside it.

Here's what I got:

   static const sigset_t term_sigs =
     1<<SIGHUP | 1<<SIGKILL | 1<<SIGTERM | 1<<SIGINT;

   static void *
   signal_thread(void *arg)
   {
     int sig;
     sigwait(&term_sigs, &sig);
     puts("signalled");
     if (pid)
       kill(pid, SIGHUP);
     exit(0);
   }

And in the main thread:

     pthread_sigmask(SIG_BLOCK, &term_sigs, 0);
     pthread_t thread;
     pthread_create(&thread, 0, signal_thread, 0);

Anything obvious missing?

Andy
