If the master accepts passive checks, it's impossible to disable host
checks completely, since some dependency checks are done without any care
to whether or not modules say "I've got this. You go back to sleep".

The only way I know of to completely block out host checks from a master
is to use Merlin as pollers, leave all the checks to pollers and set
"takeover = no" for all pollers while avoiding sending passive checks
to the master. That means the master will never be the point of origin
for any problems in the network, and dependency checks never happen.

Considering the successes of the wars on alcohol, poverty, drugs and
terror, I think we should give some serious thought to declaring war
on peace.
