Excessive CPU usage with https://github.com/dotnet/runtime

I'm experiencing this in my linux development VM for https://github.com/dotnet/runtime, running a VS Code client on Windows connected to the linux host (so cpptools runs on the linux host along with some node processes, while the UI runs outside of the linux host). Has any testing happened with that repo for this issue? It does seem to be much worse during builds, which is confusing because I got the impression that vscode takes gitignore into account for these things like it does for project-wide search and build artifact directories are ignored.

When I checked in and opened top, cpptools' cpu time total was around 65 hours, with xorg and konsole at 23 and 21 hours and node (probably the cpptools parent?) at 19. cpptools also was using about half a gig of memory (2.4g virtual).

No se especifica ningún archivo, prueba ni punto de entrada de código. Empieza reproduciendo la configuración de la VM de desarrollo de Linux con VS Code conectado desde Windows y, a continuación, observa el uso de CPU de cpptools y node durante las compilaciones. Se considera completado cuando se haya identificado la causa del uso excesivo de CPU y se haya verificado que dicho uso se reduce en el flujo de trabajo reportado.
