Indeed! I learned the hard way, a long time ago, that processes spawned from
inittab should NOT be run as daemons. That is, the process must run
synchronously -- NOT IN THE BACKGROUND -- otherwise init will think it's
gone and refork a process.

That's how I brought down our production data base server when I was a wee
lad...
