+## Throwing switches before you db:migrate ##
+
+I like to use Switches to turn off <tt>%w{memoization caching facebook campaign\_monitor delayed\_job}</tt> before running rake db:migrate, so I put this in <tt>lib/tasks/databases.rake</tt>:
+
+    namespace :db do
+      # what to do before db:migrate
+      task :before_load_config do
+        Rake::Task['s:backup'].execute
+        %w{memoization caching facebook campaign_monitor delayed_job}.each do |switch|
+          Rake::Task['s:off'].execute(Rake::TaskArguments.new([:name], [switch]))
+        end
+      end
+      # what to do after db:migrate
+      task :after_load_config do
+        Rake::Task['s:restore'].execute
+        Rake::Task['cache:clear'].execute
+      end
+    end
+
+    # make it happen
+    Rake::Task['db:migrate'].enhance(['db:before_load_config']) do
+      Rake::Task['db:after_load_config'].invoke
+    end
+
+Now my question is: how can I wrap that in a begin/ensure block so the switches are always restored?

 ## Usage ##
 
 You can do stuff like (in <tt>app/models/user.rb</tt>):
 
     after_create :subscribe_email if Switches.campaign_monitor?

 Sometimes you just need an easy way to "turn off" code.
