a function for fiberizing and defiberizing stuff that I plan to use later, maybe (untested)

gistfile1.js

_.fiberize = function (x) {
    if (typeof(x) == 'object') {
        for (var k in x)
            if (typeof(x[k]) == 'function')
                x[k] = _.fiberize(x[k])
        return x
    } else if (typeof(x) == 'function') {
        return function () {
            var args = _.toArray(arguments)
            args.push(_.p())
            x.apply(this, args)
            return _.p()
        }
    }
}

_.defib = _.defiberize = function (x) {
    if (typeof(x) == 'object') {
        for (var k in x)
            if (typeof(x[k]) == 'function')
                x[k] = _.defiberize(x[k])
        return x
    } else if (typeof(x) == 'function') {
        return function () {
            if (Fiber.current) {
                return x.apply(this, arguments)
            } else {
                var args = _.toArray(arguments)
                var cb = args.pop()
                var me = this
                _.run(function () {
                    try {
                        cb(null, x.apply(me, args))
                    } catch (e) {
                        cb(e)
                    }
                })
            }
        }
    }
}
