667	KeyError in mutable download	warner		"Zooko observed a !KeyError exception raised during mutable-file retrieval, in #651 (specifically at [source:git/src/allmydata/mutable/retrieve.py?rev=4061258c#L157]). This is a bug in the retrieval code, probably triggered by running out of valid shares. Either the {{{self.remaining_sharemap}}} mapping should not be modified while {{{download()}}} is iterating over it, or more likely {{{download()}}} must be prepared for {{{remaining_sharemap}}} to change during the iteration.
