A partial/compromise solution: what about a command-line option to "Read the options and configuration file, report any errors, and exit," like the -n option to the shells.  I realize it doesn't address 100% of everything desired, but it does allow you to check the config file syntax before proceeding to a restart.  And it's a lot easier to get the error messages from the command line, rather than having to dig them up in a log file when dnsmasq is spawned from init, inetd, or launchd. (Or is there already such an option?)

As far as coming up with a way to handle restarting dnsmasq without hiccups... I tend to agree with Brad... if you need 100% uptime, a better solution is a secondary DNS server rather than complexifying the heck out of dnsmasq.
