For (hopefully) better performance than creating a new v8::Context to wrap each callback while still avoiding leaking memory with v8::FunctionTemplate. Adds a JavaScript shim in front of module.exports.Map to wrap the req.respond API internally and preserve the public callback-passing API, while still exporting the correct prototype.
