All of the sudden (well, _somewhere_ during this afternoon) when I open either VSC or Atigravity a Julia process is launched that uses one of processor at 100% non stop. Anyone else seeing this?
It now stopped, after a 3 GB raise as well as the room temperature due to computer cooling.

I think it must be local. I’ve got Antigravity, Cursor and VS all running Julia processes and consuming over 200 threads among them with very light CPU load. (On the other hand, Elgato’s Camera Hub is eating about 50% of total CPU time between itself and its load on WindowsServer.)

Sounds a bit like it could be Revise 3.13.1, see [unexpected background thread after Revise 1.13.1 · Issue #991 · timholy/Revise.jl · GitHub](https://github.com/timholy/Revise.jl/issues/991)? Mine is at 3.13.1 here
