Unfortunately the 50% estimated saving is only for the first stage, the split 
will still fail a bit later when it creates the split files. I'll try and 
look at addressing that too, there's a few different options.

Thanks for the info about the memory requirements, useful to know - I don't 
have any real data myself yet!
