Generates a unique name. But, now the table name on disk will differ from
the table name that the user defined. Does the code handle this case: knows to
look in a registry to translate from one to the other? Would it be simpler to
create a subdirectory with uuid, and put all the tables for a session in that
directory with their original name?
