Description

I'm going to be unhelpful here and state i don't really know why this is happening, but i've noticed that the language server is using a very large amount of memory while i'm not doing anything.

I've had this instance of vscode running for about 5 hours, and jediEnabled=false.

I know it's the insider build (what's kind of frustrating for a bug report) - hope this isn't too much of an issue. Could be an insider problem i guess.

Logs

Nothing useful, last 20 lines is just "reloading modules.."
