The dependency implementation is currently "soft" and ensures correct 
start/stop/restart sequence only - it doesn't enforce child service to wait for 
parent service to become online. We will address this in future monit version 
and change the dependency to "hard" (wait for parent service to become online 
before starting child).

The start program has associated timeout which is by default 30s. You can 
modify it like this:

    start program = "/etc/init.d/httpd start" with timeout 60 seconds
