If you can't update Rails or downgrade RubyGems, you need to require 'thread' before boot.rb runs, in three files: Rakefile, script/server, and config/environment.rb. It seems older versions of Rails relied on a require from RubyGems, giving us that delightful error message upon updating RubyGems to a newer version, which does not require thread.rb by default.
