10GB memory consumption #3189
Description
When I'm running VSCode with the julia-vscode extension, I often notice that my computer gets sluggish and when I check top I find a julia process consuming just over 10GB of RAM. I can quit the process, but it keeps coming back. When I quit VSCode, the process remains, which is bad, but when I quit the process again after also quitting VSCode it stays gone and memory consumption returns to normal for good.
Here's a play-by-play recap with pastes from `top`
Status quo, my computer is sluggish and the fan is high:
