Thanks for the explanation. 

But then I do not understand why gtree.c (which is where I got my code
from) has

        node_mem_chunk = g_mem_chunk_new ("GLib GTreeNode mem chunk",
                                          sizeof (GTreeNode),
                                          1024,
                                          G_ALLOC_ONLY);

and not e.g.

        node_mem_chunk = g_mem_chunk_new ("GLib GTreeNode mem chunk",
                                          sizeof (GTreeNode),
                                          64*sizeof (GTreeNode),
                                          G_ALLOC_ONLY);

It seems at best unclear, at worst wrong
