`code --add` breaks if executed repeatedly

• VSCode Version: Code 1.18.0
• OS Version: Darwin x64 17.3.0

Executing a command like code --add path1 && code --add path2 (...) code --add pathN completely breaks the window, I only get a couple of paths added no matter what, duplicated icons in the statusbar and the entire thing basically becomes unstable/unusable.

Executing code --add path1 path2 (...) pathN works just fine, unfortunately for a high number of paths I can't submit this command to the terminal via the terminal#sendText method because of #38137.

@fabiospampinato what exactly happens in your case? For me I just see the last folder not getting added (only 2 work) and an exception in the console. Do you also see an exception?

@bpasero I've made a screencast to properly illustrate this.

Basically: I only get 2 folders, no exceptions, duplicated icons in the statusbar and the window basically freezes for a while.

@bpasero do you need "more info" from me? If so, what else is needed?

This is a race condition where the first --add request causes lots of work to happening. A pushed a change to buffer the requests for --add for 100ms before processing them. I think that should solve the issue.
