Is this better?  I suppose you don't like inline comments  
either...interesting, everyone's got their preferences...

Keep in mind that I've hacked the refclock_bancomm.c to work with my  
VME-based SYNCCLOCK32 board.  Though I am not thinking that the driver  
is the problem.

Another few data points worth mentioning is that the VME chassis is  
only on for a short amount of time, maybe 4 hours a day max.  I do have  
similar problems with a development chassis that is connected all the  
time...but, not as severe.

The SBC is a Force CPU-56, running Solaris 8.  The NTP version that  
I've modified is 1.4.2.

Here are a couple of snips of potentially worthy info (sorry for the  
length of garbage):

Around 8:00 AM I deleted the ntp.drift file...thus the improvement.
