Yeah this works great, I've used it for all my Heroku rails apps without issue
for a while now. You just put unicorn in your bundle, make a Procfile like
web: bundle exec unicorn -p $PORT -c ./config/unicorn.rb
and a config/unicorn.rb like
worker_processes 2
timeout 5 # Heroku timeout is 5s
Related: like this post[1] I'm also interested in a smarter way to trap
Heroku's SIGINT restarts into a unicorn USR2-styl restart, so we can actually
take advantage of unicorn. At high concurrency Heroku's "kill world" restarts
cause a lot of errors.
