two good arguments:
1) I'm already working on this, and you know it, since I asked you
about it in Karlsruhe.
2) 1000 is not a good choice, because we can't approximate it well
with the 8254. 1268 is better, 1381 is even better, 1903 is the
best we can do between 1000 and 2000, 2299 is the best we can do
between 1000 and 5000.
