daemondo defeats purpose of launchd?

I have this problem: the lighttpd web server on my MacBook Pro  
unexpectedly dies rather frequently (much more frequently than it did  
on my PowerBook). When this happens, the daemondo process is still  
there, and I have to use launchctl to unload and then load the  
lighttpd plist to get the server running again.

The point of launchd is that it notices when processes unexpectedly  
quit, and restarts them automatically so close to no downtime is  
observed. But launchd is monitoring daemondo, which does not exit, so  
launchd does not restart anything. And daemondo doesn't seem to have  
the same process-death-noticing feature so daemondo is not  
automatically restarting the failed lighttpd.
