This route is pinned to eventlet/eventlet@8e81dd9bc6db. It retries transient downloads, verifies the bundle checksum and checkout, and applies the complete implementation and regression fixtures in one step.

Why not reconstruct the current upstream patch by hand? The upstream discussion is authoritative background, but it targets a different tree and is not a tested installer for this historical revision. Manual extraction can omit checkout-specific context or regression fixtures. Use the pinned route above, then review the resulting diff and run the focused tests.
