BDBMinimalStorage could, and possibly should, implement
lastTransaction(), although note that because it doesn't keep object
revisions, the last transaction is the /only/ transaction that can be
accessed.  It should be easy to add by refactoring a bit of code into
the base class.

I'm not sure if that will help minimal storage to be useful in ZEO or
not though.  Maybe Jeremy can speak to that.
