Haha, got it! Thanks to gdb, I found what takes all this time:
GtkRecentManager, and particularly gtk_recent_manager_add_item(manager,
uri) at line 1037 of ui_utils.c.
Why? well, it seems to syncs its state at each and every addition, and
the g_file_set_contents(), which calls… fsync().
Commenting the addition completely fixes the problem after file loading.
Now it takes about 11 seconds, to load the files (always as reported by
the verbose messages).
Time to search for a but report on GTK I think.
