Closed Issue: VS becomes irresponsive if trying to close it after installing a bunch of npm packages [1250]

VS becomes irresponsive (won't do anything if you click on VS menus to close it or to resize it) after you install a bunch of npm packages.

I installed about 7 packages, then tried to close VS. After several clicks, VS does pop up a message in the task bar (lower right corner) indicating VS is busy and it's trying to complete a task.

Once I get myself into this state, I pretty much can't do anything at that point. Editor stopped working as well.

Repro:
- create a blank express app
- add the following npm packages through the UI
- static-favicon 1.0.0
- morgan
- cookie-parser
- body-parser
- debug
- mongodb
- mongoskin
- once completed, close the UI by clicking on the close button
- open the layout.jade file and try to type something there.
- try to close VS

At this point, VS won't close or do anything. Going back to the editor, It stopped working as well.


Comments: no longer reproduces in current build
