Looks like the ConflictError at start-up is self-inflicted: I never
stopped memcached to purge it of traces of the old/previous relstorage
database/instance I was running in my tests.  I was running
zodbconvert with --clear, but not specifying use of memcached for
zodbconvert destination storage ZConfig values, only for my zope2
instance configurations.

Lesson learned: purge memcached of any previous data via restart if
you plan to replace an existing RelStorage storage with zodbconvert
--clear.
