Memory Leak and Loop

microsoft/vscode#25796

With versions and steps to reproduce

Hello.

I was starting to write a small script with a swig library. Quickly, VSCode started to consume all memory and all swap memory until I had to reboot. I'm using VSCode 1.11.2 and OpenSuSE leap 42.1

Steps to Reproduce:

Install quickfix-python
$ sudo pip install quickfix

start a project

type the script bellow.

#!/usr/bin/env python
import quickfix

class ClientApplication(quickfix.Application):
	def __init__(self, server):
		super(ClientApplication, self).__init__()

in my case, when I trigger autocompletion within the module quickfix, that is enough to cause the loop.

Extensions:
C/C++ 0.11.0
C# 1.9.0
C++ Intellisense 0.2.1
Mono Debug 0.15.5
Python 0.6.3

Can you write that a simple Python script? Like

import jedi
jedi.Script('....').completions()

?

Oh and your Jedi release is 6 months old:

Please mention the version that you're currently using in the future. Jedi is changing quite a bit.

Oops

I just checked. It takes me a few seconds the first time to complete this. The reason is that quickfix is 1.8 MB of Python code (which is huge). This is not what the parser can handle in a reasonable time, it takes a bit more than 200 MB of RAM on my machine. Let me know if it's still an issue. (current master)
