You know, I'm not an expert on signal programming in Unix.
But, wouldn't another signal coming in during the wait cause
a the system to halt?



         for (i = 1; i < NSIG; i++)
         {
                 if (i == SIGBUS || i == SIGSEGV || i == SIGALRM)
                         continue;
                 signal (i, sig_fct);
         }


static void sig_fct (int sig)
{
         int pid, pstatus;

         sig &= 0xff;
         pid = wait (&pstatus);
         signal (sig, sig_fct);

	switch (sig)
	{
...
stuff
	}
}





This handler does nothing useful anyway except for
SIGHUP, SIGTERM, SIGBUS and SIGSEGV.  I don't see any
reason not to just ignore all signals except for the few
that do have a function here.  I'm going to let it run
like this, and see if it fixes the bug.


         for (i = 1; i < NSIG; i++)
         {
                 if (i == SIGBUS || i == SIGSEGV || i == SIGALRM)
                         continue;
                 if (i == SIGHUP || i == SIGTERM)
                         signal (i, sig_fct);
                 else    signal(i, SIG_IGN);
         }
