I want to add, that on windows, this is deadly slow. I actually expected this (before I tried it).  
The script from the first post takes 122 seconds (in `cmd`).  
PowerShell did not seem faster (EDIT: 400s).  
I also tried `wt`: it took ages as well (EDIT: 280s)  
I am not sure what terminal vscode uses by default, but it was definitely the slowest (EDIT: 1414s)

Notably I did run some of these in parallel.  
I wonder if the size of the terminal (full screen, minimized, ‘normal’) has any impact…

Maybe someone with Windows could challenge/confirm my numbers?
