I hade some problems using the Rubygems RemoteInstaller. It requires a 
'rubygems/open-uri.rb', that contains a copy of the 'open-uri.rb' file, 
that comes with Ruby. I think this was done to be compatible with older 
versions of Ruby.

I used the RemoteInstaller in an app, that used the standard 
'open-uri.rb', and I had some strange errors, because of this:

SystemStackError (stack level too deep):

Both libraries alias Kernel#open to this method and seem to confuse each 
other. I made the following patch, that solved the problem for me:

       if is_file_uri(uri)
         open(get_file_uri_path(uri), &block)

Could you appy it to Rubygems, please?
