I looked on it too - i think it will be probably better to make it more 
independent on the rest of control.c. Probably it will be better to use 
model proposed by Jan for it (dependancy matrix) => build process 
dependency relationship outside process structure (avoid use of process 
state variables).

In addition i think (again) that it will be better to use statement 
"depend foo" as declaration for "slave" processes that they depend on 
process foo, for example to define that bar depends on foo:

new proposal:

###
check foo with pidfile "/var/run/foo.pid"
...

check bar with pidfile "/var/run/bar.pid"
depend foo
...
###

instead of present:
###
check foo with pidfile "/var/run/foo.pid"
depend bar
...

check bar with pidfile "/var/run/bar.pid"
...
###

Both methods use same count of statements. Even if there will be N 
processes dependant on one process, it will require to define N times 
depend statement (in both methods).
