Easy Questions

[9mm]

Hey, this is a really great gem. So first and foremost, thanks so much for that. I have a few simple questions.

1. If I want to use monit to monitor the unicorn workers outside of the deploy hook, is there a way monit can use capistrano-unicorn for starting/stopping/restarting, so I dont need to use that unicorn_init shell script?
2. I have read about pre-loading but sadly I can't find what it's actually for. The most I can gather that it's for zero downtime deployments, and that I should be very careful if I'm using a socket (which I am).
3. Does that before/after hook still apply to rails 4?

Thanks!
