Re: [streams] can streams be transferred via postMessage()? (#276)

> * Modifying a UA-created writable stream in such a way "deopts" you to the normal pipe algorithm, since you have made it observable. This honestly seems fine to me; it's similar to how most JS objects work. (E.g. if you start adding numeric properties to Array.prototype/string-valued properties to an array, all arrays/that array will now be slow.)

I asked @bzbarsky and this option is possible, but it would probably not be our first choice.  It would require adding back features that were removed from SpiderMonkey for being a bit hacky.  It seems we should go with other options if possible.
