    I don't undstand that last line.  If 'rest_callback()' is inside of
'foo()', and it is called as 'rest_callback(time,foo)', you are going to get
infinite recursion.

    'time' is not how many times to run it, it is how LONG to run it, so
rest_callback(1, foo) should take about 0.001 seconds regardless of the speed
of foo, (as long as it is reasonably speedy), because it is being called many
times.
