(Master Branch) tsserver.js hangs in vs-code

[aozgaa]

Tested at commit c27b379 and 01244d6 .

To reproduce:

1. Build typescript (jake local).

2. In powershell:
   Copy-Item C:\<...>\typescript\public\built\local\tsserver.js C:\Users\<username>\AppData\Local\Code\app-0.5.0\resources\app\plugins\vs.language.typescript\lib\tsserver.js

3. Open up vs code. Hover over several items to get quickinfo. After a few requests, the language service writes Loading... on each hover.

On occasion, the language service was busted immediately (on the first hover), but I'm having trouble reproducing it consistently.

The source file I've been inspecting is src\services\services.ts.

This error doesn't appear to occur in Visual Studio. So it may or may not be a bug on our side.

This may or may not be related to #3887.

EDIT: It appears #3888 fixes this issue.

Can we close this then?
