I found the same thing when I originally did the ^C echo patch.  If isig() was
used instead of the order specified (flush, echo, signal), the ^C did not echo
reliably (i.e., it echoed on a tty console, but not in an xterm).  isig() does
the kill, then the flush.

Note that ^Z uses the same logic, so the fact that you are seeing this take
effect more quickly is interesting.

I will try a few things today, but please experiment with various orderings of
the calls and let me know what you find (and test the ^C echo in both tty
console and xterm).
