Description
Issue Type: Performance Issue
I keep seeing very high CPU usage by VSCode helper and child python processes of VSCode Helper. Of course, once I started writing up this issue, the processes ended 😕. From the Process Explorer, it looked like the python completion process was at fault. Sometimes Activity Monitor says there are multiple VSCode based processes using high CPU usage, but I haven't had a chance to catch those with the ProcessExplorer.
I'm not sure what causes this, since it doesn't always occur right at start up. I haven't been able to tie it to any particular file, though I have been working on the same few. It seems to be able to occur multiple times in a session. I'm not sure if this is only when I force the process to end.
