Subject: Inserting rows into GTree.tree_store is slow

I have a program which loads a file and inserts around 25,000 rows
into a GTree.tree_store model.  This process takes about 10 minutes.
I had initially blamed the (OCaml-based) loading and parsing code, but
now that I come to analyse it, it turns out that the OCaml code is
almost instantaneous (no suprise there!) but inserting the rows into
the GTree.tree_store is what is taking all the time.

I'm wondering if there is a particular reason for this.  Is it just
that the underlying C model is slow, or could it be the OCaml
bindings?  Are there good ways to "bulk insert" lots of rows into a
tree_store?

Rich.
