 gimp-2.2.4/app/core/gimppreviewcache.c uses a GSList as a sort of
    size-based queue; it holds image previews in a GSList and uses
    g_slist_insert_sorted to insert the smaller images first. Oddly,
    another function in the same file trims the cache by iterating
    over the same GSList and comparing each item to find the smallest
    one to remove. Might be a possibility for some optimization there.

The function preview_cache_remove_smallest() which is used to trim the
cache actually uses a different comparison than what is used to keep
the list sorted. Whether this is what the author intended, I don't know.

It might be of interest to your readers to also include GimpList as an
implementation of the GimpContainer class.
