Right now probably the best medicine for this problem is --resetDS. If
someone gets this and wants to investigate a little further, try doing
a --dumpDS and examining the files in the datastore to see whether one
of their ranges overlaps with the range reported in the exception.
Anyway, I have a more robust serialization system planned that I loosely
describe as journaling, where the node keeps a kind of log of additions
and deletions to the datastore with periodic commits to disk, in such a
way that the head of the log can be periodically discarded while the
tail allocates new ranges as it grows.
