For me it seems to be sufficient enough. As far as I understand for
the redundancy purposes if stop something then we have to stop
everything else, and when we start  we want everything to start.

Indeed it is not really used. The code which uses it is present but it
is permanently cut off by several  if(FALSE) statements. I'm just
commenting it out now (otherwise compiler is complaining about missing
red_update field)

At a first glance now everything seems to be OK for redundancy. At
least I can compile, link and run the redundant IOC with new base on
my PC. Still need to check two PC to see if it really works. I'll let
you know if something is missing.
