good to see that works (was kind of operating blind :-)

Yes.  The problem comes from my assumption when I wrote the code on
the old find_collision() function which has an extra argument with how
many iterations (max) to try.  Then I just call this in a loop until
clock tick rolls over.  Crude but _fast_ test :-)

(find_collision also returns how many tries it did if it finds a
collision and 0 if it did not find a collision (you know how many it
did if it did not return)).

I call it with 100 tries; but may be you'd want a bit more as the new
minters are faster. eg 256 or parameterizable maybe.

I had a amd 486dx120 somewhere gathering dust (3 x 40Mhz clock
multiplier) but I am not sure I will be able to make it work, it had
several IO cards fail and I ran out of IO cards to replace them with.
That was a sweet machine in it's time.  I was running slackware on it
(well already earlier running slackware on a 386sx16Mhz :-)
