Reviewer: Phillip Hallam-Baker
Review result: Has Issues

The document describes the problem and solution pretty clearly. Unfortunately,
there is no discussion of the security considerations which is not appropriate
for a document addressing an availability which is a security issue.

While microloops can form by chance, some consideration should be given to the
possibility that an attacker could induce a loop to perform a DoS attack.
