High CPU load node process in WSL

[ThomasHornschuh]

Issue Type: Performance Issue

Hi,
I have freshly installed Ubuntu 20.04 LTS WSL1 on my machine (before I had 18.04 LTS which I deinstalled).

Whenever I open a WSL Target, the node process in WSL (I assume the VSCode Remote Server) is running with 100% load (occupiying one thread).

VS Code version: Code 1.47.3 (91899dc, 2020-07-23T13:12:49.994Z)
OS version: Windows_NT x64 10.0.17763
Remote OS version: Linux x64 4.4.0-17763-Microsoft

Checked in the meantime that this is a WSL1 issue:
microsoft/WSL#4898

So it can be closed
