That's what I meant, in fact. Presumably, if the code needs to
allocate a new LyXText for the table, there also an old one in the
cache that should go away.

Yes, the 1.2.0cvspatched is just that. One gains 2M (to compare with
memory consumption of around 50M!). This means that undo is really not
much, compared to lyxtext.
