Sets the IO priority to use while loading directories.
Setting the priority while this is loading will reprioritize the ongoing load as soon as possible.
The default IO priority is g_priority_default, which is higher than the GTK redraw priority. If you are loading a lot of directories in parallel, lowering it to something like g_priority_default_idle may increase responsiveness.
