Rails: Running more than one rake task at once?

Been loving rails, but still struggling with how long it takes to run tasks from the command line.

I'm wondering if it's possible to combine multiple rake tasks without reloading the environment each time. For example, if I run

rails generate rspec:install && rails generate model test_model title:string && rake db:migrate

it will spend 10 seconds loading up rails to run the rspec install, then another ten seconds to load up the environment for generate model, then another for the migration. Is there a way to keep the same environment open for all 3 commands?
