After thinking some more, you are right.
Distributed monitoring can be setup with:
1. the master receiving passive service checks and checking the host
(the only way for Nagios 1.x)
2. the master receiving passive service and host check results from
the slave (http://nagios.sourceforge.net/docs/2_0/distributed.html)
This patch is fine for case 2 - this is how we setup our distributed
environment. But the patch would break case 1.
