Not yet, but I anticipate some similar problems to arise soon. QuantLib can really take a while to emulate options data, and it's not designed to do multi-threading, so I should prefer multi-process, according to Luigi Ballabio.

Thanks for the script. I probably should learn some Powershell... cmd is awkward for this task. Python also looks like a pretty good fit.

I still think I would be writing less scripting code if exec() is upgraded as described.
