Hi Folks, I apologize for accidentally tacking my post on to Uwe's yesterday. It was premature, though, as I forgot to run the specs in my excitement, so I did that last night. The addition I made doesn't seem to cause any additional failures or errors. I ran the spec:ci_19 target, but I didn't see the original failing spec come up (the one Hiro originally quoted). However, I can require 'open-uri' in 1.9 mode now.
