that is aasome - hope to see it soon in 1.5.x

What's the status on this? I can't find any discussion on the rubygems mailing list.

Apparently they attempted to do this or a similar change and it broke something else. I have no idea what the status is, and I don't have the cycles right now to follow up. Perhaps post a message to rubygems dev list and see if they can update you on progress? We're really like to ship this change for JRuby 1.6, but we don't want to hack RubyGems too much in a release.

I've started a thread about this on the rubygems dev list.
