Honestly, if you're unable to do this in 0.10, I'd say just copy out the implementation into a module, and make whatever changes you want to it. Fs streams are the simplest ones, so it's not so bad.
You might be able to subclass and just clobber the method that is calling close. I don't remember how that's implemented. But it'd be better to take that effort and spend it on upgrading instead. It might be easier than you think. At the very least, making a correctly-performing 0.10 stream is hella easier with the readable-stream module than rolling your own 0.8-style stream.
