This turned out not to be better.  Overhead caused by time
fetching and comparisons is not worth the gain.  When
percentage is printed whenever it changes, `message' is
called at most 101 times and that is cheap.  Note that 101
is a constant, while the number of constraint evaluations
is practically not limited.

So I suggest not bothering with time.  It is faster, gives
much simpler code and, finally, once per second is still to 
rarely, at least to my tastes.

Can you give a suggestion of where to place the new
functions?  Then I can produce a complete patch.
