Someday we could move Nodes execution over to vm.Script. We'd have full control over what globals were exposed to the v8 context. vm.Script also has nice support for timeouts.

What is blocking us to change this right now? The version of node that support vm.Script?

It is well supported, but that change would be a substantial refactoring.

In some server side rendering environments (e.g., `execjs` since
version 2.8.0 [1]) `setTimeout` is not available. Since
`autoSetupTimeout` runs when Video.js is imported and tries to
schedule `autoSetup`, this can lead to errors of the form in server
side rendering:
TypeError: scheduler is not a function
`autoSetup` already bailed if run outside of a browser environment or
if it has been globally disabled. To prevent calling `setTimeout`, we
move the `Dom.isReal` check into `autoSetupTimeout`. Checking
`options.autoSetup` has to remain in `autoSetup` to preserve backwards
compatiblity with apps that set the option after Video.js has loaded
but before the next tick.

Shadowed globals maybe also accessed via
this.console. This normalizes these globals across all runners. See FAQ (https://github.com/rails/execjs#faq) for why these globals should not be exposed during evaluation.Related #42.
