-// can be worked around by the chopping workaround for path building. (Once the
-// supplied chain is chopped back to just the target, a better path can be
-// found out-of-band. Normally that would be by AIA fetching, for the purposes
-// of this test the better path is supplied by a test keychain.)
-//
-// In this test, there are two possible paths to validate a leaf (A):
-// 1. A(B) -> B(C) -> C(E) -> E(E)
-// 2. A(B) -> B(F) -> F(E) -> E(E)
-//
-// A(B) -> B(C) -> C(E) is supplied to the verifier.
-// B(F) and F(E) are supplied in a test keychain.
-// C is blocked by a CRLset.
-//
-// The verifier should rollback until it just tries A(B) alone, at which point
-// it will pull B(F) & F(E) from the keychain and succeed.
