833	reject mutable children when *reading* an immutable dirnode	warner	davidsarah	"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.
