global variable is invalid when loading npm modules

[DonJayamanne]

• VSCode Version: Insiders
• OS Version: Macc

Steps to Reproduce:

1. Install Python Extension
2. Python extension fails to load

Does this issue occur when all extensions are disabled?: Yes

This applies to other extensions using reflect-metadata as well.

From what I can tell, loader.js seems to be doing something thats causing the global variable to point to something completely different.
Inside the module reflect-metadata, the value for global is:

Object {nodeRequire: }
nodeRequire:function (e){ … }
__proto__:Object {constructor: , __defineGetter__: , __defineSetter__: , …}
