netsaint. init won't do much when something like mysqld gets wedged and stops respoding. Partly because mysqld hasn't actually exited, and partly because init doesn't spawn mysqld.. but netsaint will check things like mysqld periodically and take some action when it stops responding. Usually it'll mail an admin, but you can configure it to bounce mysqld.
Netsaint no longer exists due to trademark or copyright problems (or something like that). The project was renamed to nagios and can now be found at http://www.nagios.org/. Nagios works really well for monitoring network and host health, but it is quite time consuming and complex to setup and tune to your particular environment. I probably wouldn't recommend it for monitoring / restarting a single service - the overhead just simply isn't worth it, write a simple shell script! However if you have a more complex environment with service dependencies, or services on several servers that you need to monitor then nagios can come in extremely handy. HTH.
