---------------------------+------------------------------------------------
 In #607 (DIR2-CHK), Zooko suggested that in addition to refusing to allow
 mutable children when creating an immutable dirnode, the tahoe code should
 guard against buggy/noncompliant implementations and complain when it sees
 a mutable child in a pre-existing immutable dirnode. The code should log
 an error of some sort and ignore the child.

 When I implemented #607, I didn't do this. It should be done. The
 trickiest part is testing it, and deciding where to send the error
 message.
