vscode-python: New Language Server chewing up CPU and fails on Mac

• Enable analysis engine on Mac
• Reload VS Code
• Open a python file with the following code:

import sys
print(sys)

• Hover over sys in second line

Observations

• dotnet process uses around 100% CPU
• Number of errors are logged in console window

• Edit the file
• Save changes
• Hover and intellisense works
• After around 30 seconds, cpu usage of dotnet process goes down to <1%
