A few things to manually check:

• Does datadog-setup.php need any changes? Based on how it detects support, it should Just Work but we may need to change comments or output or something.
• Have you checked Apache in the worker modes that support threading? I'd also double-check apachectl graceful.

Aside from these manual testing concerns, it looks fine to me.
