The problem there is that the Zopes reading from the duplicate storages
won't see the new transactions on the end of their Data.fs. It seems like
they read the Data.fs at startup, then stop reading it. Hm, there could
be a way to hack that into the Zope code so that when it's in readonly
mode, it looks for the Data.fs file changing size, and reads the new
stuff in... Hm, hm, hm.
