This extension brought vscode to its knees

[steve-taylor]

Type: Bug

Visual Studio Code suddently started running extremely slow. I ran Extension Bisect which found this extenson to be the culprit. After disabling it, vscode is back to normal.

I re-enabled it just to be sure and vscode was extremely slow again. I also noticed backspace no longer works when this extension is running.

Hey, can you help in reproducing it? is there some repo that it happened in?
By slowness, do you mean that saving files is slow, like #88 or just general slowness?
Or did the TS Server stop working like in #75?

BTW, I need help in reproducing those too

@onethread Thanks for the cpuprofile. Unfortunatly the CPU profile doesn't seem to show anything useful:

It just shows the extension stalling on some minified function called XX.
If you have any additional info on the project/repository where the extension started stalling that would be appreciated.
