The "safe" VDD voltage are not supposed to be flagged in the watcher.
The imager reports errors to the server (which in turn sends the information
to you watcher) if the value it measures for any voltage is different
from the value to which the imager last tried to set it.  The imager knows
that it last set the VDDs to their low values (since it always does so
at startup), so it did not complain that they were there.
The problem we want to catch is not that the VDDs are low, but that
the VDDs are low when trying to take data (because the CCDs don't
produce any signal that way).  Thus, the catch is in beginData,
actuallly all the way down in cameraStart.
