Comment (by davidsarah):

 I made the following change in mutable/retrieve.py when rebasing for
 trunk:
 {{{
 -            # Reuse the SlotReader from the servermap
 -            #print 'retrieving version:', hash(self.verinfo)
 -            try:
 -                reader = self.servermap.proxies[(self.verinfo,
 -                                                 server.get_serverid(),
 -                                                 self._storage_index,
 shnum)]
 -            except KeyError:
 -                reader = MDMFSlotReadProxy(server.get_rref(),
 -                                           self._storage_index, shnum,
 None)
 +            # Reuse the SlotReader from the servermap.
 +            key = (self.verinfo, server.get_serverid(),
 +                   self._storage_index, shnum)
 +            if key in self.servermap.proxies:
 +                reader = self.servermap.proxies[key]
 +            else:
 +                reader = MDMFSlotReadProxy(server.get_rref(),
 +                                           self._storage_index, shnum,
 None)
 }}}
