Point taken. In the general case, though, (i.e. we're talking about more than Rack awesomeness) I think it's important that people keep this in the back of their minds. I was burned on this recently with the use of the Daemon Kit gem in a project. It's definitely a "do-better" on my part to more closely examine the libs I'm working with, but as an author in a language wherein numerous OSes and implementations of the interpreter are used, it's something to keep in the back of your mind as well.
