Indeed we noticed that. However, before, while the scale change was done,
the guider images were paused for about 20 sec. It's no more the case,
they go on updating all the time.
So, what we found to get a good scale change is to insert the appropriate
change (guider scaleChange delta=xxx) then, we wait until we see "donuts"
on the guider cam (mirror is moving). The following exposure is the right
one (scale change is done).
However, I think it takes more time than before.
