Darren, as the originator of this "bug", I would be quite happy to see it 
as an option in future versions, but I would rather it was not the 
default.  I do like what you've done with the option, and it allows a very 
simple heartbeat/health-checker to be built.

By the way: I was seeing pulses every second, not just at the poll 
interval.  Poll-interval pulses (i.e. one per 16 seconds for a PPS clock 
source) would be OK with me as well, although I would /prefer/ none..
