I actually rewrote the back end of gtkclist for a project I'm working on
such that it calls a callback to get the string to print in an entry
(row/column) such that the data is only in one place and I don't have to
update it.  Its part of a logic wave trace viewer I'm working on to hook
into our processor simulator, actually (coincidence?).

And there are some linked lists in there, though I think my version
removed the worst offenders (because of the back end rewrite I don't
have to keep track of data on a per cell basis, currently).

The code isn't finished yet, but I could probably clean it up a bit and
send it to you.
