Section 9.1.2 says:

The Phase 2 decision function is blocked from running while the Phase
3 decision function is in process.

It should say:

The Phase 3 decision function is blocked from running while the Phase
2 decision function is in process.

Notes:

I believe that is what was intended; the text as is confuses me no end.
--VERIFIER NOTES--
It is accepted that the RFC text is confusing, but the proposed errata text is incorrect because this proposed revision implies that Phase 2 can begin running while Phase 3 is still running this contradicts other text in the RFC (9.1.2) which states that "The Phase 3 Routing Decision function is blocked from running whilst the Phase 2 decision function is in process."

It is anticipated that the IDR WG will publish material clarifying mutual exclusion in RFC4271.
