A brute-force method I used for a while for apache was this (in the  
cron), may be wrapped but is supposed to be on 1 line:

/bin/sh -c "ps `cat ${HTTPDHOME}/www/logs/httpd.pid` | fgrep -s  
'/usr/local/bin/httpd' || /usr/local/bin/httpd -d ${HTTPDHOME}/www"

I guess similar methods could be used for other daemons as well.
