When I do $ rake assets:precompile from the command line twice, then the assets are only generated once (as expected).
When I execute system 'rake assets:precompile' twice within a Ruby file, then the assets are also only generated once (as expected).
But when I execute it once from the command line and once from the Ruby file, then the assets are generated twice!

Why's that? And how can it be prevented? Thank you.
The reason why I'm doing this:
I'm searching for unused CSS selectors throughout my application. I forked the old DeadWeight gem and updated it so it's working with newer versions of Rails.
The problem is that I need the fully compiled application.css file when initializing DeadWeight, so I precompile it from within DeadWeight. And there I noticed that when there's already a precompiled version that was precompiled from the console (and not from within DeadWeight), it's not overwritten! So I have to manually remove it first (by doing another rake assets:clobber/clean) which isn't nice.
