> I thought I'd found another bug because one of 4 variants didn't have a loop,
> but then I noticed that the method in question was being fed a list, and the
> very first thing it does is loop that list... so it seems there is no need to
> loop the list, create and pass in a singleton list, and then have the method
> loop that singleton list to process a single item...
> Fixing this should save us a bit of object creation & therefore reduce GC
> load.
