My understanding of those messages is that Mnesia has reached the
startup option "-mnesia dump_log_write_threshold Max" (Max's default =
100) before the last log dump finished.  It's a sign that you're busy.
Mostly harmless.

Does R9C-0 require both mnesia:change_table_copy_type/3 and
mnesia:add_table_copy/3?  In newer versions, only the former is
necessary.
