Related to #9212

Approach
Only call process.children(recursive=True) once per report.

  • PR title captures the intent of the changes, and is fitting for release notes.
  • Added appropriate release note label
  • Commit history is consistent and clean, in line with the contribution guidelines.
  • Make sure unit tests pass locally after every commit (git rebase -i main --exec 'pytest tests/ert/unit_tests -n logical -m "not integration_test"')

When applicable

  • When there are user facing changes: Updated documentation
  • New behavior or changes to existing untested code: Ensured that unit tests are added (See Ground Rules).
  • Large PR: Prepare changes in small commits for more convenient review
  • Bug fix: Add regression test for the bug
  • Bug fix: Create Backport PR to latest release
