Then our tests change the `$LOAD_PATH` to make test gems installed in tmp visible to `require`, and then they all require `cgi` as a transitive dependency of `rack-test`, this time from `tmp` gems. This causes system and test specific copies to be mixed together and these warnings to be printed, but we have also observed failures in some tests with errors like > class variable @@accept_charset of CGI::Util is overtaken by CGI::Escape This changes should also fix those failures. The fix is to require all of `rack-test` (including `cgi`) before we have changed the `$LOAD_PATH`. Because the `$LOAD_PATH` is unchanged, RubyGems respects the version of `cgi` activated by RSpec, avoiding the double loads. https://github.com/rubygems/rubygems/commit/34e75465c6
