Hi!

Is there any known exploit against real programs using this technique?
The technique seems to work in a very low probability level due to
the timing issues. But the first thing I have learned reading bugtraq
is that if something is even remotely and theoretically exploitable,
someone is using the technique for years already (and openbsd have
fixed it two years ago:).
