The resolution is pretty simple: 

class NewApp < Sinatra::Default   

  before do
    ActiveRecord::Base.connection.verify!
  end
...
end #end of Sinatra class

I created a Lighthouse ticket before I discovered the resolution. There are also more technical details here: https://thin.lighthouseapp.com/projects/7212-thin/tickets/101-activerecord-connection-does-not-reconnect-when-using-thinsinatra-but-works-fine-with-just-sinatra#ticket-101-4
