	Stratum 5 would not be an appropriate number for a machine whose 
refclock has wigged out.  Stratum 16 would be more appropriate in 
that case.

	But it would definitely be good if the GPS refclock drivers could 
be updated to consider additional information such as EPE or HDOP, so 
that they would be more likely to know when their information is good 
and when it is not.
