One other cause is your :dependent callbacks.

    class Blog < AR::Base
      has_many :posts, :dependent => :destroy
    end

This will iterate through every post and call #destroy on it.  Use :delete_all if you want to just issue a single delete query.  HOWEVER, this won't hit your destroy callbacks on Post.

    class Blog < AR::Base
      has_many :posts

## example_note_keeping_app.rb
require 'rubygems'
require 'sinatra'
require 'redis'

# To use, simply start your Redis server and boot this
# example app with:
#   ruby example_note_keeping_app.rb
#
# Point your browser to http://localhost:4567 and enjoy!
