And I suspect I am one of the few people using display groups to drive 
my alerting. I resisted defining alert groups back in the BB days 
because it seemed like too much work. When I moved to Xymon and I could 
leverage my existing display groups, I jumped on board.

With these patches, my non-production server running 4.3.22 on Solaris 
10 is running much better. This is very encouraging :)

Looking at the patch files and reading the new source, am I correct it 
adds a couple of startup options to xymond_alert?
   --reload-interval=number-of-seconds
   --loadhostsfromxymond
where the first specifies the number of seconds after which the contents 
of hosts.cfg should be reloaded, and the second says hosts.cfg could be 
retrieved from xymond rather than the filesystem (similar to the 
existing option for xymongen).
