Subject: rubygems implementation question

I was curious why the code in installer.rb in ruby gems was setup like this?

I thought mkdir_p checks to make sure of the existance of a dir before 
creating it, and quietly fails if it already exists, making the 
additional check seem odd.  Is there a particular reason for this?

        unless File.exist? File.join(install_dir, "specifications")
          FileUtils.mkdir_p File.join(install_dir, "specifications")
        end
        unless File.exist? File.join(install_dir, "cache")
          FileUtils.mkdir_p File.join(install_dir, "cache")
        end

Also, I wasn't quite sure on this, is require_gem supposed to 
automatically get a package if it's not local the first time it runs or no?
