Table RENAME is pretty risky under 6.5 :-(. 7.0 is a little better,
but RENAME will never be trustworthy until we abandon the linkage
between file names and table names.

You could probably get away with
CREATE TABLE someothername (same parameters)
and then rm the (presumably 0-size) file 'someothername' and copy the
original-table-named file to that file name. This will not fill the
indexes, if any, on the new table, so drop and recreate them afterwards.
After that, update to 7.0.2 ;-)
