$ ruby --inspect test/scorpio_test.rb

I encountered this error output running a ruby program with --inspect, but the ruby process continued with the chrome debugger attached. I think this happened when I was removing breakpoints in chrome (not entirely sure; I had hit 'resume' before I noticed the error output), and in this debug session, execution is stopping on a breakpoint I had clicked remove on, and which is not visible in chrome.
