I'm not sure why it happens, normally editing FRM should be enough.  My
guess is that TokuDB supports table discovery (that's a fact, not a
guess yet), and it stores frm somewhere inside TokuDB tablespace, and
when you edit the frm file, TokuDB noticed the difference and
"discovers" the original FRM. And overwrites your edits.

ALTER TABLE would do, I suppose.
Although, of course, that's far for an ideal solution.
