God defines 1.kilobyte == 1. ActiveSupport has always defined 1.kilobyte == 1024. IMHO, god should not patch core classes at all... God is not a language extension, it is a process monitoring tool. If I want such language additions as Numeric::kilobytes I will load ActiveSupport to provide it. Gems that redefine core class behaviour cause all sorts of problems. Can you either change this behaviour to return 1024, or just remove it entirely?

Thanks, I'll close this ticket and continue the discussion there ;)
