Stupid o'clock

The last few working days have been quite productive. Admittedly, I have been working until stupid o'clock in the morning, as today. I've been giving my individual project a bit of a tidy up, as I need it to generate lots of different options, preferably without crashing before it gets there. It started running 90 minutes ago and appears to still be alive! Last week it would have consumed all the system memory and crashed by now. I still need to make it even faster and less memory
hungry, but I have a theory.

It's probably time to leave this overnight...
