Motivation
I still can't seem to reproduce #2681, but the only way I can think of launching multiple workspaces is if some other VS Code extension is causing numerous
didOpenTextDocument
events to be launched all at the same time.In theory, if that happens we could find ourselves in a race condition, because launching the workspace takes a while.
Implementation
This PR tries to fix the problem by remembering which workspaces are being activated. We then return early if multiple documents are causing the lazy activation of the same workspace.
