Hi Alexander,

I hope I'm understanding you correctly, so you want the master process
to die if you've misdeployed or misconfigured your app?

This is one of those sharp edges of Unicorn that might be pointless
to protect against with preload_app=false...

The general rule is that you shouldn't be mucking around with Gem (or
any other library) installations on a production server unless you're
deploying.  And whenever you're deploying, you would always be checking
to see you've deployed correctly anyways, so you can detect any screwups
in the installation/deployment.

Let me know if that makes sense.
