> In the spidermonkey engine, we use a built-in function sealing for sealing documents so that map functions of arrays no longer works. Array sealing no longer works with javascript 1.8, meaning our document that contain arrays cannot be sealed. The sealing is meant to prevent map functions from modifying the same document that will be passed to other map functions.
> The (hopefully temporary) fix here is to simply remove the document sealing, and map function placed in the same design document will have to be trustworthy that they don't modify the document (the same document is passed to multiple map functions). Non-trustworthy map functions can be placed in their own design documents, they will be run in isolation.
