Yep, this seems fine now. Many thanks Miroslav and Bill! 
Your direction was invaluable in resolving the adjtimex() 
and shmget() problems.

I have temporarily reverted my workaround for the "high Last 
Sample value for PPS0" potential chrony bug we discussed and 
turned on refclock & tracking logging as suggested. 
Hopefully through this I'll be able to come up with some 
data that might go towards identifying and/or solving a 
chrony bug. The least I can do. :)

Thanks
Tom
