I guess it's this code:

- (void)fd_handler:(id)unused
/* --------------------------------------------------------------------------
     Check data waiting on file descriptors and terminate if so.
   -------------------------------------------------------------------------- */
{
[...]
          result = select (selfds[0]+1, &fds, NULL, NULL, NULL);
          if (result > 0 && read (selfds[0], &c, 1) == 1 && c == 'g')
	    waiting = 0;

nsterm.m uses pselect throughout otherwise, so I guess changing this to
pselect should be unproblematic, too?  Perhaps Alan has some comments;
added to the CCs.
