Process timeout on git clone with composer update

The process "git clone --mirror -- 'https://github.com/drupal/core.git' '/m  
  nt/ddev-global-cache/composer/vcs/https---github.com-drupal-core.git/'" exc  
  eeded the timeout of 2000 seconds.

This is after putting "process-timeout": 0 under "config" in the composer.json file.
