Now I finally understand how people are using this trick. I believe this 
is mostly used for mocking domain classes (Rails models, for instance) 
when using ActiveRecord or Sequel, given their metaprogramming tricks on 
initialization to fetch the tables meta-data.

But I don't see how this ticket would affect such environments. If I 
understand correctly, what Koichi proposed is to replace require with 
require_relative on Ruby stdlibs and core classes only. Do you see any 
reason you'd like to execute those files? I believe they won't touch any 
database or network so they shouldn't slow down any tests, right?

Cheers,
Rodrigo.
