* macOS Actions runners have 3 vCPUs. No wonder this wasn't working. Reduce the success count to 1.

* Brute force the conditions required to make this work. Issue 128 jobs.

* Record status(s) and just verify they're non-zero. Checking for exact values is difficult when you don't know the hardware ahead of time.
* Apply HOLD state

* Increasing sleep times might help.

* test_envctl_init
* test_envctl_register

* test_mp_fail_fast
* test_mp_stop_continue

* test_pip_index_provides
* test_conda_provides
* test_conda_get_active_environment
* test_delivery_gather_tool_versions

Fix tests:

* global.sysconfdir duplicates the environment string
* Use delivery_free()
* Use globals_free()

* delivery_gather_tool_versions now returns non-zero if unable to determine a tool's version

* The user can choose to (not) run the long scripted statis test(s)
